branchMergePreview(branchId: ID!, targetBranchId: ID): BranchMergePreview!

Requires project.read.

Arguments

Argument	Type	Required	Description
`branchId`	`ID!`	Yes	Branch to merge. A missing branch and one the caller cannot read are both not found.
`targetBranchId`	`ID`	No	Target branch ID; omit for main.

Response

Returns BranchMergePreview!. Open the type for its fields and nested types.

Field	Type	Description
`sourceBranch`	`Branch!`
`targetBranchId`	`ID`	Branch that receives the merge, or null for main.
`targetBranchName`	`String!`
`canMerge`	`Boolean!`	True only when blockedReason is null, merge policies pass and no file has conflicts. Advisory: the merge checks these conditions again.
`blockedReason`	`String`	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.
`hasConflicts`	`Boolean!`
`diffs`	`[BranchMergeFileDiff!]!`

Types marked with ! cannot be null. Lists use [Type] notation. The type index lists all published input and response types.
