Configuring CodeStream to integrate with Trello is a bit different than the other services. Trello provides a Developer API Key to all accounts. You cannot change it.

Login to Trello and Navigate to the Developer API Key Page

Login to trello using the account whose Developer Key you wish to use for integrating with CodeStream. Once you're logged in, you can see your key by going to .

developer key

Update the Origins

Add your CodeStream On-Prem server callback URL as a New Allowed Origin. The redirect URL should reference your company's CodeStream On-Prem hostname with this path:

Update the CodeStream Config and Restart

Update your codestream config file, ~/.codestream/codestream-services-config.json, by adding the following section.

	"integrations": {
		"trello": {
			"cloud": {
				"apiKey": "-- Developer Key goes here --"

After you make that change, restart CodeStream

~/.codestream/codestream --restart

Instruct your users to Reload their IDEs. They should now be able to connect to Trello.
