Can I replace SimpleTalk and keep GoHighLevel?
Yes. Assistable connects to GoHighLevel for CRM and booking workflows, so you can keep the locations, contacts and calendars your business controls. Reconnect each location, map the call trigger and returned outcomes, then test a complete call and appointment. This replaces the agreed workflow; SimpleTalk credentials and webhook requests do not transfer unchanged.
Key points
- Start with one HighLevel location and a contact your team controls.
- Connect the CRM, map the fields and prove the booking in the real calendar.
- Switch the calling trigger only after the full workflow passes.
Keep HighLevel as your system of record
You do not have to abandon the HighLevel workflow your team knows. Use an Assistable subaccount connected to the client’s HighLevel location, then map the calling trigger and returned result. Authorizing the connection does not rewrite existing automations for you.
Assistable also supports Direct subaccounts without HighLevel. That is a different setup. The current v3 documentation limits its Appointments resource to HighLevel-connected subaccounts, so do not choose Direct expecting that booking API to work unchanged.
1. Connect one location first
Pick a location you are authorized to manage. Record its HighLevel location ID, the matching Assistable subaccount and the person who owns each connection. Authorize the HighLevel integration for that location, then verify that its contact fields and calendars are available.
Choose a test contact and calendar before enabling any calling trigger. Use a number your team controls. Keep customer-facing reminders and downstream outreach out of this test audience.
- Confirm the business name and location ID, not only a familiar calendar name.
- Verify access to the contact, relevant fields, conversation history and intended calendar.
- For a custom v3 integration, use a scoped key and the target X-Subaccount-Id. An Assistable subaccount ID is not interchangeable with a HighLevel location ID.
- Resolve missing access before testing writes or starting calls.
2. Map the pieces your workflow uses
Start with the existing SimpleTalk workflow and one known contact. Its documentation uses the HighLevel contact ID to associate conversations with a person. Preserve that identity and the meaning of each outcome when building the replacement.
| Existing piece | Record before changing it | Acceptance check |
|---|---|---|
| Location and contact | HighLevel location ID, contact ID and corresponding Assistable subaccount | The result reaches that contact in that location. |
| Call trigger | Workflow entry rule, wait steps, retry rule and eligible audience | One eligible test contact receives one intended call. |
| Contact fields | Field IDs, data types, allowed values and blank-value behavior | Correct data enters the conversation and returns to the intended field. |
| Outcome and follow-up | Meaning of each tag or result, plus the workflow it starts | Qualified, booked, unanswered and opted-out results start only the intended action. |
| Calendar | Calendar ID, service, owner, duration, hours and time zone | One appointment appears for the correct contact and time. |
| Human handoff | Destination, staffed hours, context and unanswered-call rule | The person receives the call or the agreed follow-up reaches its owner. |
3. Connect availability and booking
Sync the location’s calendars into Assistable and select the actual calendar ID. Enable availability lookup and appointment booking for the agent. If the workflow includes rescheduling, also configure retrieval and update of existing appointments.
Define the sequence: identify the contact, check availability, confirm the selected date and time zone, then book. For multiple calendars, map each service or team member to its calendar ID. Specify what happens when no suitable slot exists.
Run a booking with the test contact, then inspect the saved appointment in HighLevel. Confirm the contact, calendar, duration and time zone. A spoken confirmation alone is not proof of a booking.
4. Return the result and hand off exceptions
Connect the agreed outcome to its contact field, tag or follow-up action. Keep “call completed,” “lead qualified” and “appointment booked” as separate results. Check where your team sees the conversation and who receives an unfinished request.
If the old automation sends a SimpleTalk webhook, map its URL, authentication, identifiers and payload to the new connection. Do not paste the old request into a different provider and assume the contract is the same.
Define the human path for a failed booking, unanswered transfer or missing CRM update. Name the person or queue that owns it and include the contact and call reference needed to follow up.
5. Pass these checks before switching
Use the same test contact across the call, CRM and calendar. Record the call reference and actual result for each scenario. These are acceptance checks to perform, not reported migration results.
| Test | Passing result |
|---|---|
| Normal booking | Correct contact, one appointment, correct calendar and time zone; intended follow-up runs once. |
| No availability | No invented time or appointment; the approved alternative or callback path is used. |
| Missing contact detail | The agent asks for the required information or follows its fallback without inventing it. |
| Opt-out | The request is recorded and further outreach is suppressed by the configured rule. |
| Answered and unanswered transfer | The intended person receives the call; the unanswered path reaches its owner. |
| Repeated result in the test workflow | Replaying the event does not create another appointment or follow-up. |
| Expired or unavailable connection | Failure is visible to the operator and the agent does not claim an action succeeded. |
6. Switch one audience, then repeat
Record the test approval, switch time and first audience. Check pending waits and retries in HighLevel, then stop the old SimpleTalk calling action for that audience before enabling the replacement. Keep a working fallback and a named owner for early calls.
For agencies, repeat the access, field, calendar and handoff checks for each client. A shared agent template does not make client-specific identifiers or permissions interchangeable.
Common questions
Do I need a new GoHighLevel account?
You can keep the HighLevel locations and records your business controls. The migration reconnects Assistable and updates the calling and follow-up automation needed for the agreed workflow.
Does Assistable work without HighLevel?
Yes. Assistable Direct stores contacts, conversations and messages in Assistable. Its current v3 documentation says the Appointments resource remains HighLevel-scoped. Confirm the booking integration required for your deployment.
Will my existing SimpleTalk webhook work unchanged?
Do not assume so. Use the existing request to identify the required behavior, then map its endpoint, authentication and fields to Assistable. Test the returned outcome and any retries before switching.
Can I move multiple HighLevel client subaccounts?
Plan one mapping per client: HighLevel location, Assistable subaccount, permissions, contact fields, calendars, numbers and handoffs. Start with one representative workflow, then validate each client before moving its traffic.
What proves that the migration is working?
Inspect the result in HighLevel: the right contact, correct fields, one appointment and the intended follow-up. Also test no availability, opt-out, failed handoff and repeated events. A successful-sounding call alone is not enough.
Will my HighLevel workflows keep running unchanged?
The location and customer records you control can stay. Replace the SimpleTalk-specific calling action, credentials or webhook as needed, then verify the outcome fields and follow-up rules. Keep one active calling trigger for the test audience to avoid duplicate outreach.
