In business automation
Credentials provide an authorized connection between a workflow and an external service. Storing them in a dedicated place makes it possible to use the same connection across multiple workflows and replace it without scattering secrets through code.
Examples
These examples illustrate a possible workflow. Adapt the connections and rules to your own systems.
Business process example
Several workflows update the same CRM through a configured organizational connection. When a key is replaced, the connection is updated and one workflow of each action type is checked before marking the transition complete.
Relevant tools
- n8n
- Credentials are managed separately from workflow business data and are used to connect to nodes.
What to check
- Check who can use the credentials, not only who can view them. Permission to run a workflow can allow an action even without exposing the secret.
