Getting the connection_uris of a branch via API

I know that when I create a branch with a connection, I’ll get the connection_uris in the response object. Is it possible to get the connection_uris from an existing branch? I did not find it in the swagger docs unfortunately. If not, then this would be a feature request :slight_smile:

Hi @ThibaultJanBeyer ,

To ensure I understand your use case correctly, do you need the API to return a connection_uri from a branch id? What other parameter are you using?

You can get the PGHOST of a branch using the<PROJECT_ID>/branches/<BRANCH_ID>/endpoints endpoint.

curl --request GET \
     --url<PROJECT_ID>/branches/<BRANCH_ID>/endpoints \
     --header 'accept: application/json' \
     --header 'authorization: Bearer API_KEY'

You will get the following result:

  "endpoints": [
      "host": "",
      "id": "ep-gentle-night-193152",
      "project_id": "morning-meadow-820265",
      "branch_id": "br-cool-silence-987406",

See the API reference for more detail.

You can then construct your branch connection string like so: postgres://PGUSER:PGPASSWORD@PGHOST/PGDATABASE

However, dynamically reconstructing your connection string is not recommended as it is prone to error.

Please let me know if this helps.

Hi, yes I wanted to create a CLI for local development that prompts the user to either select an existing NEON branch or create a new one if none exist yet to work with locally. Creating a new one returns the connection_uri which I can just use to inject into the .env file kinda like you did in the script on branch creation however, for using an existing one I would have to create it dynamically like you answered which is not ideal

Thanks for clarifying and for your feedback. I’ll share this with the team.
