Connecting Make.com

No dedicated module needed — HTTP → Make a request is enough.

Send an SMS from a scenario

1. Add an HTTP → Make a request module.
2. URL: https://smsprovider-web.vercel.app/api/v1/messages · Method: POST.
3. Headers:

• Authorization: Bearer bm_live_… (store it as a keychain/connection)
• Content-Type: application/json
• Idempotency-Key: {{uuid}} (Make's uuid function, or a unique id from the trigger — so a re-run never sends twice)

1. Body type: Raw · Content type: JSON:

{ "to": "{{1.phone}}", "from": "MyBrand", "body": "Hi {{1.first_name}}, your appointment is confirmed for {{1.date}}", "ref": "{{1.id}}" }

1. Enable Parse response to get messages[].id.

Receiving events in Make

1. Create a scenario with Webhooks → Custom webhook and copy its URL.
2. Register it: POST https://smsprovider-web.vercel.app/api/v1/webhooks with the events you want (e.g. inbound.received).
3. For full security verify X-Batler-Signature (see Webhooks) — at minimum deduplicate on X-Batler-Event-Id.

OTP in a form

Two HTTP modules: POST /otp/send when the user enters a phone, and POST /otp/verify with the code. Continue only if verified is true.
