n8n
Point n8n at the Build docs and your key, paste one sentence, and let it write the call.
Use n8n for: something on a schedule. It reads the same docs as every other tool.
Where the key goes
Store the key in an n8n credential and add it to the HTTP Request node as the X-API-Key header. The key is always named BUILD_API_KEY, and the prompt names the variable, never the key.

The prompt
Paste this into n8n. It points your AI at the docs and at your key, then says what you want.
Read https://build.sellermate.ai/SKILL.md. My key is in BUILD_API_KEY. Every Monday at 8, post each client’s spend, sales, ACoS and change vs last week to our team channel.
A worked example
To write: a worked example in n8n: the prompt, what n8n writes, the call it makes to Build, and what you check before you run it
Expected output
The example above should end with: Monday cards in #client-reports.
To write: a screenshot or sample of the real output for this prompt
If it breaks
Paste the error back into n8n. Errors say what to change, and a 429 says when to retry. Reads are safe to run again.
