Agent Tool testing blocked by credits

Hi guys,

I am building Agent Tool support for Renewal Radar and I’ve run into a pretty frustrating blocker.

The official way to test Agent Tools is through HubSpot’s Developer Tool Testing Agent. Since July 23, that uses HubSpot Credits.

My developer test account has no credits, and when I try to add them, the only option I get is “Contact Sales”.

So how are app developers supposed to properly test Agent Tools before submitting them?

Integration is basically ready to test, but right now I’m blocked by the credit setup rather than the actual development.

Has anyone found a way around this, or is there a developer credit option I’m missing?

Hey @Ulasarslan !

The Developer Sandbox should have a separate credit allocation from your test account, have you tried testing through there instead?

Also flagging in some folks who may have context here: @KlemenHrovat @miljkovicmisa @HubSpot_Corey has anyone navigated the credits issue for Agent Tool testing specifically?

Thanks Cassie. That’s exactly where I’m a bit confused.

We’re following the Agent Tool development flow in the HubSpot docs. The tools are deployed successfully and visible in a developer test account, but that account has 0 HubSpot Credits, so the Developer Tool Testing Agent can’t run.

I understood a Developer Sandbox to be a separate environment, rather than something required for Marketplace Agent Tool development.

If the intended approach is to use a Developer Sandbox because it has its own credit allocation, happy to try that. It would just be helpful to clarify, since the current Agent Tool docs point developers to a developer test account.

Hi everyone,

@Ulasarslan and I connected on this directly, but sharing the resolution here for anyone who runs into the same issue.

The credit error comes from using the Run button, which executes the agent like a live agent and draws on credits. That’s not the path for tool testing. Instead, use the built-in Test agent function inside the agent’s Configure view:

  1. Open the Developer Tool Testing Agent and click Configure (top right)
  2. Under What this agent can access, click Add tool and confirm your agent tool is added
  3. Enter a prompt in the Your message field
  4. Click Test agent — not Run

The Test agent button is the supported testing flow and won’t hit the credit gate the way a live run does. Full walkthrough here: Create an agent tool (BETA) - HubSpot docs

One other thing worth checking: make sure your developer account is opted into the Breeze Agent Tools on the HubSpot Developer Platform beta, as that’s a prerequisite for this testing flow.
