# Zapier

> Point Zapier at the Build docs and your key, paste one sentence, and let it write the call.

Use Zapier for: something on a schedule. It reads the same docs as every other tool.

## Where the key goes

Keep the key in the Zap step that calls Build, as the `X-API-Key` header, and not in a field that is shared. The key is always named `BUILD_API_KEY`, and the prompt names the variable, never the key.

_To write: the exact steps and a screenshot for putting BUILD_API_KEY into Zapier_

## The prompt

Paste this into Zapier. It points your AI at the docs and at your key, then says what you want.

Prompt for zapier:

```
Read https://build.sellermate.ai/SKILL.md. My key is in BUILD_API_KEY. Email me every Monday revenue, ad spend and TACoS, Amazon and Google Ads side by side.
```

## A worked example

_To write: a worked example in Zapier: the prompt, what Zapier writes, the call it makes to Build, and what you check before you run it_

## Expected output

The example above should end with: Monday email scheduled.

_To write: a screenshot or sample of the real output for this prompt_

## If it breaks

Paste the error back into Zapier. Errors say what to change, and a `429` says when to retry. Reads are safe to run again.
