Quo (OpenPhone)

Known limitations of Quo API

Limited visibility of contacts created via API

If you've created contacts in Quo via Relay.app, you may have noticed that the contacts were created successfully, but you're not able to see them in your contacts list. This is due to a limitation of the Quo API where contacts may be created via their API, but are not visible until there is an associated conversation.

From Quo's documentation here:

Visibility in the Quo app

After creating an API contact, it will only appear in the Quo app—whether in the conversation list, contact list, or search results—if there’s an associated conversation with a matching phone number.

Working with Quo

I'm getting an error that I am out of credits.

The Quo API requires API credits to send messages. These are different from Suno AI credits (and Relay.app credits). You can see how to purchase API messaging credits in Quo's documentation here.
