What are runtime tokens?

Runtime tokens (prefix jfn_rt_) are credentials that authenticate requests to your functions in production.

​
Automatic generation

The first deploy generates a token automatically: 
jelou deploy
# ✓ Deployed
# ⚠ A default runtime token was created for this function.
#   Save it now — it will not be shown again.
# ▸ Token    jfn_rt_abc123...
The token is shown only once. Subsequent deploys don’t show it. If you lose it, create a new one with jelou tokens create.

​
How to use

Send the token in the X-Jelou-Token header: 
curl -X POST https://my-function.fn.jelou.ai \
  -H "Content-Type: application/json" \
  -H "X-Jelou-Token: jfn_rt_abc123..." \
  -d '{"phone": "593987654321"}'

CLI management

# List tokens
jelou tokens list my-function

# Create additional token
jelou tokens create my-function --name ci-deploy
Creating a token triggers an automatic redeploy of your function. The code doesn’t change, but the platform needs to update the available tokens in the runtime environment.
# Revoke token
jelou tokens revoke my-function <token-id> -y
Revoking a token also triggers an automatic redeploy. Clients using that token will start receiving 401 once the redeploy completes.

​
Multiple tokens

You can have multiple active tokens per function — one per environment, service, or team. Revoking one doesn’t affect others.

​
Lost token?

Create a new one: jelou tokens create my-function --name new-token. The old token stays active.
