Sendblue lets the assistant answer an iMessage, RCS or SMS conversation from a Sendblue sender number. A customer texts that number and the reply goes back on the same service.

​
When to use it

Use it when you already send Apple Messages or SMS through Sendblue and want the assistant in that thread. The sender number must be a Sendblue line in E.164 format, for example +15551234567.

​
What the assistant hears

The assistant hears inbound messages delivered to a receive webhook. iMessage, SMS and RCS are the services this connection accepts.

​
Where the keys come from

The linked provider guide shows the screens for these clicks. Follow the clicks below together with those pictures. Copy the API Key ID and API Secret Key from the credentials screen in the Sendblue dashboard. You choose the webhook signing secret yourself, so it exists before the Famulor URL. The dashboard path for the webhook is documented, with the setup screens, in Sendblue webhooks: Developer → Webhooks, type receive. Sendblue sends the secret in the sb-signing-secret header.

​
Create it at the provider

  1. Sign in to the Sendblue dashboard.
  2. Copy the API Key ID and the API Secret Key from the account credentials.
  3. Copy the sender number in E.164 format.
  4. Invent a webhook signing secret and keep it. You will paste the same value into Famulor and into the receive webhook.

​
Connect it in Famulor

Your plan includes this channel. Open Settings → Channels, choose the card, name the connection, pick an assistant and save. The shared conversation settings — response delay (default 5 seconds) and inactivity timeout (default 30 minutes) — are described on the messaging channels page. On the Sendblue card paste Sendblue API Key ID, Sendblue API Secret Key, Sendblue sender number (E.164) and Webhook signing secret. After saving, open the connection menu and choose Copy webhook URL. Paste that exact address into the provider. A verified custom domain is already part of the address Famulor shows.

​
Point the provider at Famulor

  1. Copy the Famulor webhook URL.
  2. In the Sendblue dashboard open Developer → Webhooks.
  3. Add a webhook of type receive. Set the URL to the Famulor address and the secret to the value you saved in Famulor.
  4. Text the sender number. The conversation appears in History.

​
History

Open History and filter by Sendblue. The thread, the assistant reply and any analysis appear there. You can pause the assistant and answer manually.

API, MCP and command line

The same connection can be created with the public API, the MCP tool create_messaging_connector, or the command line. Replace the placeholders with your own values.
