Popular questions
- What are active rows?Active rows are the rows inserted or updated in your destination in a month, and they are what plans are measured in.
- How often can syncs run?It depends on the plan: daily on Basic, hourly on Premium, every 15 minutes on Business and every 5 minutes on Enterprise, with faster schedules available as add-ons.
- Rows I deleted in the source still show up. Why?Incremental syncs only pick up new and changed rows, so a row deleted in the source stays in your warehouse until the table is fully synced again.
- How do I re-authorize a connector, or connect it as a different user?Go to Settings → Connectors, open the connection, then Configuration → Authorize, and sign in with the account you want Weld to use.
- A sync failed. What should I do?Open the sync to see the error. Weld explains it and suggests a fix, and says whether you need to act: a Delayed sync retries on its own, while a Failed one usually needs something from you, such as re-authorizing the connector.
- My database is behind a firewall. How does Weld connect?Allow Weld's IP addresses: 3.64.84.139, 3.65.119.169 and 35.156.133.78.
- Is there a free trial?Yes. Every plan starts with a 14-day free trial with full access and no credit card, and usage during the trial isn't billed.
- When is support available, and how fast do you respond?Monday to Friday, 9:00 to 17:00 Copenhagen time. How fast we respond depends on the problem's severity and the support level on your plan: Basic on every plan, Premium on Premium, and Priority on Business and Enterprise, where a critical issue gets a first response within 15 minutes.
