}Authorizations
Use a JWT bearer token or a Veryfront API key in the Authorization header.
Path Parameters
Project slug, UUID, or domain that identifies the project.
Branch UUID belonging to the selected project. Missing or foreign branches return 404.
Query Parameters
Target branch ID; omit for main.
Response
Merge preview.
Branch to merge.
Show child attributes
Show child attributes
Branch that receives the merge, or null for main.
Name of the branch that receives the merge.
True only when blocked_reason is null, merge policies pass and no file has conflicts. Advisory: the merge checks these conditions again.
Precondition that blocks the merge, such as a merged or closed branch, or a target that is the source branch or is closed; null when none does. A target that is missing or in another project is a not found error.
Whether at least one file has conflicts.
File-by-file changes the merge applies.
