The platform signs in to other services to do its work: one to read the product's code and pull requests, one to read its tickets, and one for each destination it publishes to. Each of these sign-ins is a connection. Each product chooses which connection it uses for each job, so different teams can use different accounts.
Reading a connection
Each connection has a card:
- Check connection: Checks the connection again (signed-in administrators only).
- Connected: The connection's status. Connected means its last check succeeded; Error or Needs re-authorization means it needs attention.
- Last checked and Used by: When the platform last asked the service which account the credentials belong to, and which products use the connection, and for what.

Signed-in administrators also see the account it signs in as, the site it connects to, the message from its last check and its recent activity. These details are hidden from anyone who is not signed in. When a connection stops working, Connections in the sidebar shows how many connections are failing.
To add a connection:
1. Click Connections

2. Click Add a connection

3. Choose the Account type. The list shows the services the platform can connect to

4. Enter a Name that describes the account, such as Acme code repositories, and the Site address if the form asks for one

5. Enter the account's credentials. For an Atlassian account, enter the Account email and the API token; other services ask for what they need, such as an access token

6. Click Add and check. The platform saves the connection and checks it straight away

Credentials are stored encrypted and are never shown again, even to administrators.
To replace a connection's credentials:
1. On the connection's card, expand Replace credentials
2. Enter the replacement credentials, then click Replace and check
To delete a connection:
Important: Delete connection is unavailable while a product uses the connection. To delete it, open Config, choose a different connection for each product that uses it, then come back to Connections and click Delete connection.
