| Goal | API |
| --- | --- |
| Create a sequence policy to configure a unique, sequential number for all posted invoices and credit memos. | [Create a Sequence Policy API](https://developer.salesforce.com/docs/atlas.en-us.revenue_lifecycle_management_dev_guide.meta/revenue_lifecycle_management_dev_guide/connect_resources_create_sequence_policy.htm) |
| Update the settings of a sequence policy that defines how unique, sequential numbers are generated by using specific patterns, values, and filters. | [Update Sequence Policy API](https://developer.salesforce.com/docs/atlas.en-us.revenue_lifecycle_management_dev_guide.meta/revenue_lifecycle_management_dev_guide/connect_resources_update_sequence_policies.htm) |
| Assign sequence pattern values to objects based on the configured sequence policy. | [Sequence Assignment API](https://developer.salesforce.com/docs/atlas.en-us.revenue_lifecycle_management_dev_guide.meta/revenue_lifecycle_management_dev_guide/connect_resources_sequences_assignment.htm) |
| Restore a missing sequence value identified by using this API in gapless-enabled sequences. This sequence value can be used later in the subsequent sequence policy numbering, ensuring there are no gaps. | [Sequence Gap Reconciliation API](https://developer.salesforce.com/docs/atlas.en-us.revenue_lifecycle_management_dev_guide.meta/revenue_lifecycle_management_dev_guide/connect_resources_sequences_gap_reconciliation.htm) |
