Build your integration in the free sandbox before preparing for production.
Your measurement choice is reused on this site and can be turned off. Account association requires separate consent.
Choose the integration layer after listing the work your application must own. A provider account and a wrapper are different things.
If one provider meets your task and your team already owns callbacks, state storage, retries and access rules, evaluate a direct integration first. An additional layer must justify its operational cost.
Compare a runnable workflow for persistent state, duplicate-event handling and explicit unavailable outcomes. Use the same task and failure branches on both sides; do not assume that an MCP or SDK alone saves implementation time.
Run success, reject and unavailable branches below. These are synthetic integration outcomes. They prove branch handling, not provider rights, identity approval or a production customer result.
Record your task, chosen provider, required evidence, recovery owner and actual test results. Measure elapsed work yourself; no unmeasured time saving or price advantage is claimed.
A successful demo is one checkpoint. Verify service access, consent, recovery and your application action separately.
Name the event, country, provider product and required fields. Number validity does not prove ownership; an identity result does not grant your application permissions.
Confirm the current account entitlement, permitted use, required consent and data handling before real requests. A public research listing is not commercial access.
Check the provider result, the received notification where required, the local state and the intended action in your application. Do not replace missing evidence with a sandbox response.
The example below is synthetic and free of upstream calls. A production request needs its separate readiness checks. Real self-service payments remain disabled; do not top up to unlock an unconfirmed capability.
Build a scoped estimate from the task and supplier evidence. Separate query charges from integration and ongoing operations.
Specify one task, country, expected volume range and the result your application needs. List unknown fields and unsupported branches instead of assuming global coverage.
Collect the current supplier quote, product tier, billing unit, minimums and applicable taxes. Keep integration work and ongoing recovery or maintenance separate. No public price is asserted here.
Assign duplicate-event handling, timeouts, user retry and manual review. A low query price alone does not establish the lowest total operating cost.
Run the synthetic example, then prepare task scope and required capability for an access assessment. No payment is accepted by this example; production scope and supplier rights require confirmation.
Selecting an entry records your content choice, not proof of watching.
Build the first identity onboarding result handler before collecting any document. This walkthrough uses an account-free synthetic response; it does not create a hosted provider session. Your application must keep verification decisions separate from seller permissions.
Add a pre-registration number check while keeping invalid numbers separate from unavailable results. A format or validity signal cannot prove ownership or SMS reachability. This walkthrough returns no line type and sends no OTP.
Recover a delayed callback without creating duplicate sessions. The runnable local example stores state in SQLite, enforces a deadline and rejects late permission grants. Its callback channel is explicitly synthetic: it is not a live signature verifier.
Turn a verification result into a bounded application decision. Test account binding, explicit policy, duplicate events and rejection handling in a local fixture database. The permission shown in this walkthrough is a demo flag, not a real seller permission.
