You are integrating Didit's Phone Verification module into <my_stack>.
Follow these steps exactly. Every URL, header, and enum value below is
canonical — do not paraphrase or "improve" them.
## 1. Provision an account
- Sign up: https://business.didit.me (no credit card required).
- Or provision programmatically: POST https://apx.didit.me/auth/v2/programmatic/register/
(returns an API key bound to the workspace + application).
## 2. Two integration paths — pick one
### Path A — Workflow Builder (hosted UI)
Best when you want Didit to handle phone collection, country prefix UX,
channel routing, OTP entry, resend buttons, mobile/desktop handoff, and
accessibility for you.
1. Create a workflow that contains the PHONE feature:
POST https://verification.didit.me/v3/workflows/
Authorization header: x-api-key: <your-api-key>
Body: workflow_label, features array with the single entry
{ feature: "PHONE" } (UPPERCASE — strict enum)
Optional config: preferred_channel ("SMS" | "WHATSAPP" | "TELEGRAM" |
"RCS" | "VIBER" | "CALL"), code_validity_seconds, max_code_attempts
(default 2), max_resend_requests_per_24h (default 2).
2. Create a verification session for an end user:
POST https://verification.didit.me/v3/session/
Body: workflow_id (from step 1), vendor_data (your own user id),
optional contact_details.phone in E.164 format
(e.g. "+14155552671") to pre-fill and lock the number.
Response: session_url — redirect the user to it.
3. Listen for webhook callbacks (see "Webhooks" below).
### Path B — Standalone server-to-server API
Best when you already own the phone-entry UX (mobile SDK, native
onboarding app, reseller pipeline) and want Didit to handle OTP delivery
+ risk scoring only. Two endpoints, called in sequence:
Step 1 — Send the code:
POST https://verification.didit.me/v3/phone/send/
Content-Type: application/json
Body fields:
- phone_number (required, string, E.164 format e.g. "+14155552671")
- channel (optional — "SMS" | "WHATSAPP" | "TELEGRAM" | "RCS" |
"VIBER" | "CALL". Omit to let Didit pick the best
available channel for the destination country and
carrier — automatic fallback routing.)
- vendor_data (optional, your user id for cross-session linkage)
Step 2 — Check the code:
POST https://verification.didit.me/v3/phone/check/
Content-Type: application/json
Body fields:
- phone_number (required, same E.164 number)
- code (required, the OTP the user typed)
- vendor_data (optional, same user id used in Step 1)
Response: JSON report — status, verification_method (the channel that
actually delivered), carrier object, is_disposable, is_virtual, warnings
array.
## 3. Channel routing — how the automatic fallback works
When channel is omitted on /v3/phone/send/, Didit picks the cheapest
+ most-deliverable channel for the destination:
- SMS where deliverable and lowest cost (most countries)
- WhatsApp in BR / IN / MX and other WhatsApp-dense markets
- Telegram / RCS / Viber where carrier-side SMS is blocked or premium
- CALL (voice OTP) as last-resort fallback when text channels fail
Each retry attempt may switch channels — the final delivery channel is
returned as verification_method in the report.
## 4. Webhooks (Path A only — Path B returns synchronously)
- Register a webhook destination once via
POST https://verification.didit.me/v3/webhook/destinations/
Body: url, subscribed_events: ["session.verified", "session.review_started",
"session.declined"]
- Response includes secret_shared_key — store it.
- Every webhook delivery carries an X-Signature-V2 header you MUST verify
before trusting the payload. HMAC-SHA256 verification MUST run against the raw body bytes (the raw payload as Didit sent it) BEFORE any JSON parsing — re-serialising the parsed body changes whitespace and key order, which invalidates the signature.Algorithm:
1. sortKeys(payload) recursively
2. shortenFloats (truncate trailing zeros after the decimal point)
3. JSON.stringify the result
4. HMAC-SHA256 with the secret_shared_key
5. Hex-encode, compare to the X-Signature-V2 header.
## 5. Reading the report (both paths return the same phone object)
- status: "Approved" | "Declined" | "In Review" | "Not Finished"
- phone_number_prefix: country prefix in international format ("+34")
- phone_number: subscriber number without the prefix
- full_number: full E.164 string ("+34600600600")
- country_code: ISO 3166-1 alpha-2 ("ES")
- country_name: full country name
- carrier: { name, type: "mobile" | "landline" | "voip" | "unknown" }
- is_disposable: boolean — temporary or throwaway number
- is_virtual: boolean — VoIP or virtual provider
- verification_method: the channel that actually delivered the code
("sms" | "whatsapp" | "viber" | "telegram" | "call")
- verification_attempts: number of code-entry tries
- verified_at: ISO 8601 timestamp
- warnings: Array<{ risk, log_type, short_description, long_description }>
Auto-decline risks (always enforced by Didit, not configurable):
- VERIFICATION_CODE_ATTEMPTS_EXCEEDED
- HIGH_RISK_PHONE_NUMBER
- PHONE_NUMBER_IN_BLOCKLIST
Configurable risks (action per workflow — Decline, Review, or Approve):
- DISPOSABLE_NUMBER_DETECTED
- VOIP_NUMBER_DETECTED
- DUPLICATED_PHONE_NUMBER
## 6. Attempt limits (defaults — overridable per workflow)
- Max code-entry attempts: 2 per session
- Max resend requests: 2 per phone number per 24 hours
- Code validity: 5 minutes from send
Hitting either limit fires VERIFICATION_CODE_ATTEMPTS_EXCEEDED and
auto-declines the session.
## 7. Hard rules — do not change
- Base URL for /v3/* endpoints is verification.didit.me (NOT apx.didit.me).
- Feature enum is UPPERCASE: PHONE, ID_VERIFICATION, LIVENESS, FACE_MATCH,
AML, IP_ANALYSIS.
- Channel enum is UPPERCASE on input ("SMS", "WHATSAPP", "TELEGRAM",
"RCS", "VIBER", "CALL") and lowercase on output ("sms", "whatsapp",
"telegram", "rcs", "viber", "call").
- All phone numbers go in and come out as E.164 strings — including
the leading "+" and country prefix.
- Auth header is x-api-key (lowercase, hyphenated).
- Webhook signature header is X-Signature-V2 (NOT X-Signature).
- Always verify webhook signatures before trusting payload data.
- Status casing matches exactly: "Approved", "Declined", "In Review",
"Not Finished" (title-cased, space-separated).
## 8. Pricing reference (public)
- Didit fee: $0.03 per verification (the cheapest channel; some
channels and countries cost more — see didit.me/pricing for the
per-country, per-channel table).
- Carrier fee: variable by country and channel, billed as a
pass-through with no Didit markup.
- You only pay when a message is SENT. If the user abandons before
delivery, you are not charged.
## 9. Verify your integration
- Sandbox starts on signup at https://business.didit.me — no separate flag.
- Sandbox numbers: deterministic E.164 numbers return Approved by default;
trigger Declined with the canonical "high-risk" sandbox number.
- Switch to live: flip the application's environment toggle in console.

Didit is infrastructure for identity and fraud, the platform we wished existed when we were building products ourselves: open, flexible, and developer-friendly, so it works as a real part of your stack instead of a black box you integrate around.
One API covers verifying people (KYC, know your customer), verifying businesses (KYB, know your business), screening crypto wallets (KYT, know your transaction), and monitoring transactions in real time, on a stack built to be:
The footprint underneath: 14,000+ document types in 48+ languages, 1,000+ data sources, and 200+ fraud signals on every session. The Didit infrastructure dynamically learns from every session and gets better every day.
PHONE feature flag. SMS as the default and lowest-cost channel for most countries. WhatsApp in WhatsApp-dense markets like Brazil, India, and Mexico. Telegram and Rich Communication Services (RCS) where carrier-side SMS is blocked or premium-priced. Voice (call) as the last-resort fallback when text channels fail. Pin a channel per workflow when policy demands it, or omit channel on POST /v3/phone/send/ to let Didit pick the cheapest deliverable hop. The channel that actually delivered is returned as verification_method on the report. Full per-country availability at docs.didit.me/core-technology/phone-verification/overview.phone JSON object on the session decision endpoint, or returned inline from POST /v3/phone/check/. Top-level status is one of Approved, Declined, In Review, or Not Finished. The object also includes phone_number_prefix, phone_number, full_number (E.164), country_code (ISO 3166-1 alpha-2), country_name, a carrier block (name, type is mobile or landline or voip or unknown), the is_disposable flag for temporary or throwaway numbers, the is_virtual flag for VoIP and virtual providers, verification_method (the channel that delivered, sms, whatsapp, telegram, rcs, viber, call), verification_attempts, verified_at as an ISO 8601 timestamp, and a warnings array. Full reference at docs.didit.me/core-technology/phone-verification/report-phone-verification.The full flow normally takes under 30 seconds end-to-end, pick up the ID, snap the document, snap the selfie, done. That is the fastest in the market. Legacy KYC providers usually take more than 90 seconds for the same flow.
On the back end, Didit returns the result in under two seconds at p99, measured from the moment the user finishes the selfie to the moment your webhook fires. Mobile capture is tuned for slow phones and slow networks: progressive image compression, lazy software development kit load, and a one-tap hand-off from desktop to phone via QR code if the user starts on web.
VERIFICATION_CODE_ATTEMPTS_EXCEEDED and auto-declines. (2) Phone-number risk signals, HIGH_RISK_PHONE_NUMBER for known-bad reputation, PHONE_NUMBER_IN_BLOCKLIST for your own blocklist, DISPOSABLE_NUMBER_DETECTED for throwaway providers, VOIP_NUMBER_DETECTED for Voice over Internet Protocol numbers, DUPLICATED_PHONE_NUMBER for the same number across different vendor_data users. (3) Cross-session matches, the same phone number across different users surfaces on the matches array so you can catch ring-fraud and synthetic identities. Full catalog at docs.didit.me/core-technology/phone-verification/warnings-phone-verification.Every session lands on one of seven clear statuses, so your code always knows what to do:
Approved, every check passed. Move the user forward.Declined, one or more checks failed. You can allow the user to resubmit the specific failed step (for example, re-take the selfie) without re-running the whole flow.In Review, flagged for compliance review. Open the case in the console, see every signal, decide approve or decline.In Progress, user is mid-flow.Not Started, link sent, user has not opened it yet. Send a reminder if it sits too long.Abandoned, user opened the link but did not finish in time. Re-engage or expire.Expired, the session link aged out. Create a new session.A signed webhook fires on every status change, so your database always stays in sync. Abandoned and declined sessions are free.
Production data is processed and stored in the European Union by default, on Amazon Web Services. Enterprise contracts can request alternative regions for jurisdictions whose regulators require it.
Encryption everywhere. AES-256 at rest across every database, object store, and backup. Transport Layer Security 1.3 in transit on every API call, webhook, and Business Console session. Biometric data is encrypted under a separate Customer Master Key.
Retention is yours to control. Default retention is indefinite (unlimited) unless you configure shorter, between 30 days and 10 years per application, and you can delete any individual session at any time from the dashboard or the API.
Certifications: SOC 2 Type 1 (Type 2 audit in progress), ISO/IEC 27001:2022, iBeta Level 1 PAD, and a public attestation from Spain''s Tesoro / SEPBLAC / CNMV that Didit''s remote identity verification is safer than verifying someone in person. Full report at /security-compliance.
Didit ships compliant by default for the regulators that matter to identity infrastructure:
