Troubleshooting Flow Retries

Time Based Retry

If a flow interview encounters an unhandled error, the transaction is rolled back and some flows schedule a time-based retry. A time-based retry restarts flow interviews from start or resume on a schedule with intervals typically lasting at least one minute, and often longer.

Callout Actions

This flow follows the general process for making a callout: The callout must occur before Salesforce records are updated, because Salesforce doesn’t allow updates to its records before accessing data outside Salesforce. Consider this flow after it’s saved.

• A callout that updates data outside Salesforce: Update External Opportunity that uses an External Services action
• Updates Salesforce data: Update an Opportunity based on the results from the External Services action

If, in a batch of two flow interviews, one fails its callout while the other completes and updates Salesforce records, no rollback or retry occurs because the failing interview made no Salesforce updates.

If, in a batch of two flow interviews, both succeed in their callouts but one fails its updates to Salesforce while the other succeeds, the successful flow rolls back and retries, with a maximum of 2 retries.

Actions that perform callouts can’t be rolled back.

Not every flow element that appears to require a callout does.

Fault Paths

A fault path connected to an element handles all errors occurring on that element, and it's the only way to guarantee that a flow interview doesn't fail and that retries aren't attempted. See Customize What Happens When a Flow Fails.
