Overview
This guide walks you through setting up a Vercel log drain to send logs into Bronto.Prerequisites
Before configuring the drain in Vercel, you’ll need a Bronto API key with at least the Ingestion role.Create a Bronto API Key
- In Bronto, navigate to Settings → API Keys
- Click Create API Key
- Give the key a descriptive name (e.g.,
vercel-log-drain) - Assign at minimum the Ingestion role
- Copy the generated API key — you’ll need it when configuring the drain headers below
Configure the Log Drain in Vercel
- Navigate to your team settings in Vercel and go to the Drains section
- Click Add Drain in the top-right corner
- Select Logs as the type of data to associate with this drain
- Configure the log drain name and select which projects should be associated with this drain
All data associated with a single drain configuration will be grouped in the same dataset. We recommend creating multiple drains to separate projects and environments.
- Select the log sources and environments (e.g., production, preview) you want to include
- Optionally configure sampling to reduce Vercel drain costs
- Select Custom Endpoint and set the URL to your Bronto ingestion endpoint:
Do not append
/v1/logs to the URL. Use the base ingestion URL only. Ensure you replace <region> with your Bronto account’s region (eu or us).- Select NDJSON as the format
- Add the following custom headers:
| Header | Value |
|---|---|
x-bronto-api-key | <your_api_key> |
x-bronto-service-name | <dataset_name> |
x-bronto-service-namespace | <collection_name> |
- Click Test — if everything is configured correctly you should see a 200 status response
If you receive an error, double-check that the endpoint URL does not include
/v1/logs, the API key has the Ingestion role assigned, and all three custom headers are present and correctly formatted. If issues persist, contact Bronto Support.- Click Create Drain to finish setup
