Acumbamail API Authentication

How to authenticate Acumbamail API requests: one Bearer API key plus a connectionId. MindCloud stores your API key securely — set it once, never resend it.

Every Acumbamail API request through MindCloud needs two things: a MindCloud API Key and a connectionId for your Acumbamail account. This page covers both, plus exactly how to send them, so you do not need to visit any other page to get authenticated.

Steps to authenticate

Create a MindCloud account at app.mindcloud.co if you do not already have one.
Generate a MindCloud API Key in API Keys. This is the Bearer token you send on every request. Keep it on your server.
Create a Acumbamail connection in Connections. Acumbamail uses an API key. You generate the key in your Acumbamail account, then paste it in when you create the connection — MindCloud stores it securely and never returns it in a response.
Copy the connection’s connectionId — you will send it on every request alongside your MindCloud API Key.

How requests are authenticated

Authentication has two layers. Your MindCloud API Key authenticates the request to MindCloud, sent as a Bearer token in the Authorization header. The connectionId selects the connected Acumbamail account that should run the action. MindCloud stores and refreshes the Acumbamail credentials behind that connection, so you never send provider tokens with your requests.

Pass connectionId in the query string for GET and DELETE actions, and in the JSON body for POST, PUT, and PATCH actions.

For example, calling List Lists with an Acumbamail connection looks like this:

curl --request POST \
  --url "https://connect.mindcloud.co/v2/universal/apps/acumbamail/actions/list-lists/run" \
  --header "Authorization: Bearer $MINDCLOUD_API_KEY" \
  --header "Content-Type: application/json" \
  --data '{
  "connectionId": "$CONNECTION_ID",
  "arguments": {}
}'

The Authorization: Bearer <your MindCloud API Key> header authenticates you to MindCloud; the connectionId tells MindCloud which Acumbamail account to run the action against. Missing or invalid Authorization returns 401, and a missing or mismatched connectionId returns 400.

Connect Acumbamail with an auth token

You need an active Acumbamail account with API access.

Sign in to Acumbamail
Open Acumbamail and sign in with the account you want to connect.
Open the API documentation page
Go to the Acumbamail API docs and review the authentication section.
Copy your auth token
From the API docs authentication section, copy the auth_token shown for your logged-in account.
Paste token in MindCloud connection
In the Acumbamail connection form, paste the token in the API Key field and save.

Keep your key safe

Keep your MindCloud API Key on your server; do not ship it in browser code, mobile apps, public repositories, or logs. Anyone with the key can call the Universal API as your MindCloud account, across every connection you have created.
