Send work to your Grok Bot from another app with a webhook

Beginner · How-to · Oct. 25, 2026

If you do part of your work in another app or AI tool, you don't have to copy and paste it over to your Grok Bot. A routine can start when another app calls it over the web, and the Bot gets what that app sent.

That call is a webhook: a web address that another app sends a message to. The official changelog added it Aug. 19 (v0.21.0): "Routines can start from a webhook, with their own Webhook URL and Webhook key." Six days later (v0.27.0, Aug. 25) it added, "Routines started by a webhook receive the request body, so your Bot can act on what was sent."

What's inside

A webhook routine has three parts, per the Routines help page:

The instruction. What the Bot does each time it runs, same as any routine.
The URL. The address the other app sends to. The help page labels it "POST to."
The key. The secret for that address. Senders include it as Authorization: Bearer <key>. The help page also shows a "header" field, which is that full line, ready to copy.

The sending app can include a JSON body, and the Bot receives that body with the routine's instruction, the help page says. JSON is labeled text, like {"task": "Summarize this report"}.

Set it up

In chat, tell the Bot what the routine should do with incoming work. For example: "Make a routine that takes any task sent to it and does it, then posts the result in this chat." The help page says to "Ask the Bot to add a webhook trigger to the routine."
On desktop, click the Bot's name at the top of the chat, find Routines on the Details tab and open the routine.
Find the Webhook section. Click a field to copy it. An Oct. 22 changelog entry says the key "stays hidden until you reveal it."
Give the URL and header to the app that will send work. Per the help page, the sender makes an HTTP POST to that URL with the header.

The help page's phone steps don't list the Webhook fields, so do this part on desktop.

Check that it worked

The help page says a response of 200 "means Grok Bot accepted the call and started a run. It does not mean the Bot has finished the instruction." Look in the Bot's chat for the result.

"Any other response means a run did not start," the help page says. Check that the routine isn't paused and that the sender used the current key.

A ready-made template

Moritz Kremb (@moritzkremb on X) posted a Grok Bot template Oct. 24 that he said "lets ChatGPT, Claude Code or any other agent send tasks to your Grok Bot." Adding it gives you "a webhook URL, key and one ready-made prompt" to paste into the other tool, his post says. The Grokbotlist directory lists it as Bridge Bot. GG has not tested it.

Keep it safe

Treat the key like a password. Anyone with the URL and key can start your routine. Don't paste the key into a public chat, a shared doc or a post.
Treat what arrives as untrusted. The Bot acts on the body it receives. Write the instruction so the Bot does only the job you named, and keep anything that sends email, spends money or deletes files behind an approval.
Watch usage. Each run spends usage, the help page says. A sender that calls the webhook constantly runs the routine constantly. See how often should a routine run.
Use Test with a safe input. "A test does real work," the help page says.

What to do with it

Pick one job you keep moving by hand between apps, and make a webhook routine just for that.
Copy the header field instead of typing the key, so the sender gets it exactly right.
After your first call, confirm you got a 200 and then check the Bot's chat for the result.
If you ever share the key by mistake, pause the routine right away. Neither the help page nor the changelog says how to get a new key.
