# How to replace SimpleTalk APIs and webhooks.

Map the requests, identifiers and outcomes behind your SimpleTalk integrations, then test the replacement without duplicate calls or missing CRM updates.

## Can I keep my SimpleTalk API and webhook workflows?

You can rebuild the same business workflow, but check the new endpoint, credentials, fields and event behavior. Start with one request and follow it through to the real CRM update or booking. Test repeated events and failed actions before switching live traffic so retries cannot create duplicate calls or appointments.

Save redacted examples of a successful request and a failure.
Map what each field means and which customer it belongs to.
Test repeats, late events and failed actions before changing the live route.

## Start with one request and its result

Choose one integration, such as a HighLevel action that starts a call. Record what sends the request, what receives it and what should happen afterward. Include the callback that updates the customer record or triggers a follow-up.

Save a redacted request, response and result event from authorized logs. Note who manages the credentials, but keep the credentials themselves outside the examples.

SimpleTalk's documentation describes webhook-driven calling. Use the existing setup as a reference for the job to reproduce, not as an assumed drop-in request format.

| Part | What to record | What to test |
| --- | --- | --- |
| Access | Credential owner and required permissions | The right integration can act; an unauthorized one cannot |
| Request | Required fields, formats and defaults | Blank or invalid values produce a clear result |
| Identifiers | Contact, location, agent and call references | The outcome reaches the right customer |
| Response | How acceptance, failure and completion are reported | A queued request is distinguishable from completed work |
| Result events | Outcome, timestamp and matching call identifier | Repeated or late events are handled correctly |
| Business actions | Bookings, tags, tasks and follow-ups | Each intended action happens once |

## Map meaning as well as field names

A completed call is not always a qualified lead. Keep transport status, conversation outcome and business result separate so the replacement does not trigger the wrong follow-up.

Check phone formats, timestamp time zones, units and defaults for blank values. Include any context that your existing middleware adds automatically.

For each field, record its source, meaning, destination and any conversion. Mark unanswered mappings before you test; do not silently fill them with guesses.

## Test the failures that repeat work

A timeout may leave the sender unsure whether a call was accepted. A result may arrive twice or after a newer update. Use a test setup to check these cases before customers are involved.

1. **Send the same result twice** Confirm it does not create a second call, appointment or staff task.
2. **Deliver an older result late** Check that it cannot overwrite a newer completed state or reopen finished work.
3. **Make the next action fail** Confirm the failure is visible and has a retry or manual follow-up, rather than being recorded as success.
4. **Use invalid test credentials** Check that the problem reaches an operator and retries do not continue without a limit.
5. **Remove optional information** Confirm missing context leads to the intended default, clarification or fallback.

## Switch one route, then check the results

Move a controlled route or audience first. Stop the old producer from sending the same work. Keep the identifiers needed to match calls with results across the switch.

Check already-queued calls before changing the route again. Restoring an old URL does not undo a booking or cancel work that another system accepted.

Give your team a short way to trace a request, find the outcome and reach the person responsible for a failed connection. Then expand to the next integration.

## Frequently asked questions

### Can I replace the SimpleTalk URL and keep the same payload?

Do not assume that. Check the destination's authentication, required fields, identifiers and result events, then test the complete workflow.

### How do I prevent duplicate appointments from webhooks?

Test repeated and late events in the receiving workflow. It should recognize work already completed and avoid creating the same business action again.

### Should I switch every integration together?

Start with a route whose calls and results you can track. Check queued work and dependencies before expanding the change.
