Use ChatGPT to manage your Chartcastr automations with natural language. This guide walks you through setting up a Custom GPT that connects to your account.

​
Prerequisites

  • A ChatGPT Plus subscription (required for Custom GPTs)
  • A Chartcastr account with at least one source configured

​
Step 1: Generate an API Key

  1. Go to Settings → Credentials in your Chartcastr dashboard
  2. Click Generate Key to create a new API key
  3. Copy the key immediately - you won’t be able to see it again
Store your API key securely. Never share it publicly or commit it to version control.

​
Step 2: Create a Custom GPT

  1. Go to ChatGPT GPTs
  2. Click Create a GPT
  3. Give it a name like “Chartcastr”
  4. Add a description: “Manage Chartcastr chart automations”

​
Step 3: Configure Actions

  1. In the GPT editor, go to Configure > Actions
  2. Click Create new action
  3. Click Import from URL and enter:
https://public.api.chartcastr.com/v1/openapi.yaml
  1. Under Authentication, select API Key
  2. Set the header name to X-API-Key
  3. Paste your API key from Step 1

​
Step 4: Add Instructions

In the Instructions field, add: 
You help users manage their Chartcastr account. Chartcastr automates chart deliveries from your data sources to Slack.

You can:
- List sources (charts from your data sources)
- Get the latest AI analysis (pulse) for any source — chart image, short summary, and full analysis

For anything else (managing connections, OAuth, settings) direct users to chartcastr.com/admin.

​
Step 5: Verify the Connection

  1. Save your GPT
  2. Start a conversation and ask: “List my sources”
  3. If everything is configured correctly, you’ll see your Chartcastr sources

​
Troubleshooting

Double-check that your API key is correctly entered in the Actions authentication settings. Make sure there are no extra spaces.
Ensure the OpenAPI URL is correctly imported. Try removing and re-adding the action.
The Custom GPT can list your sources and destinations, but creating new connections requires OAuth flows. Use the Chartcastr dashboard for that.

​
What You Can Do

Once connected, you can ask ChatGPT to:
  • “List all my chart sources”
  • “Show my Slack destinations”
  • “What connections do I have set up?”
  • “Get the latest analysis for [source name]”
  • “Verify my connection with code 123456”
