Interakt + AI voice calls: a WhatsApp nudge for every missed call

1. 01

   Get the template approved in Interakt

   Create the template in Interakt and wait for Meta approval. Note its code name and language code.
2. 02

   Copy your Interakt API key

   In Interakt open Settings → Developer Settings and copy the API key.
3. 03

   Optional: create an API campaign for reporting

   Create an Interakt API campaign for the template and note the campaign id, so sends show in Interakt's reports.
4. 04

   Add the step in a Vyora Workflow

   After the Call (and If / else "They didn't answer" for missed calls only), add "Send to another app" with Interakt's address, the Basic auth header and the JSON body.
5. 05

   Test with your own number, then publish

   Run a test, let it ring out, and check the run log reads "Sent to api.interakt.ai (200)".

Add the header in the step with name Authorization and value Basic followed by a space and your key, exactly as Interakt shows it in Developer Settings.

{
  "countryCode": "+91",
  "phoneNumber": "{{callee_number_local}}",
  "callbackData": "vyora_call_{{call_id}}",
  "type": "Template",
  "template": {
    "name": "missed_call_followup",
    "languageCode": "en",
    "bodyValues": ["{{callee_name}}"]
  }
}

name is the template's code name: in Interakt it is the part of the template's URL between template/ and /view, not the display title. callbackData (up to 512 characters) comes back in Interakt's delivery webhooks, so putting the Vyora call id there lets you match a WhatsApp status to the call.

Interakt rejects a number that includes the country code or starts with 0. Vyora stores numbers as +919876543210, so use the field made for this:

Interakt fills body variables in order from bodyValues: first value into {{1}}, second into {{2}}. Only include headerValues or buttonValues if the template actually has header or dynamic-button variables.

A Hindi template that confirms the callback time the lead gave the agent, with a campaign id so it shows in Interakt's reports:

{
  "countryCode": "+91",
  "phoneNumber": "{{callee_number_local}}",
  "campaignId": "YOUR_INTERAKT_CAMPAIGN_ID",
  "type": "Template",
  "template": {
    "name": "callback_slot_hi",
    "languageCode": "hi",
    "bodyValues": ["{{callee_name}}", "{{answer.callback_time}}"]
  }
}

{{answer.callback_time}} exists only when the agent collects a Post-Call Analysis field called callback_time, so use this on the "They answered" branch.
