Setup guide

Send WhatsApp messages from REST API

Trigger a WhatsApp template from WATick whenever something happens in REST API.

  1. Get your API details

    Open Settings → API Access & Webhook in your WATick panel to find your API details and documentation.

  2. Create templates

    Create and get approval for the templates your app will send.

  3. Call the API

    Your developers send an HTTP request with the phone number, template name and variables.

  4. Handle responses

    Save the message ID and handle errors, like an invalid number.

  5. Receive updates

    Turn on the webhook to receive delivery, read and reply events.

Best practices

Tips for smooth automation

Follow these tips so your messages reach customers every time.

Use the right number formatCountry code + number, no + or leading 0 – for example 917620798265.
Use approved templatesOutside the 24-hour chat window, WhatsApp only allows approved templates.
Message opted-in customersOnly send to people who agreed to hear from you. It keeps your quality rating high.
Test with your own numberRun the workflow once with your number before switching it on for customers.
Keep your token privateStore the API token in the tool’s secure credentials – never in public pages.
Watch for errorsAdd an error path or notification so you know if a message could not be sent.

📥 Also possible: get replies in REST API

Turn on the webhook in your WATick panel and every WhatsApp reply can flow back into REST API – to update a lead, add a note, save to a sheet or alert your team.
