) A single step within a flow.

| Field | Type | Description | |---|---|---| | match_rule | [bitdrift.public.unary.workflows.v1.MatchRule](bitdrift_public_unary_workflows_v1_MatchRule.md "bitdrift.public.unary.workflows.v1.MatchRule") | The step's match rule. This rule must be satisfied to advance to the next step in the flow. | | exit_conditions | array of [bitdrift.public.unary.workflows.v1.Step.ExitCondition](#bitdrift.public.unary.workflows.v1.Step.ExitCondition "bitdrift.public.unary.workflows.v1.Step.ExitCondition")
up to 100 items | Zero or more exit conditions for the step. If an exit condition is met, the flow resets to the start of the flow. | | loop_match_id | optional string
up to 100 chars | Describes an optional loop condition that allows looping back to a previous step in the flow. Must point to the match ID in the same step or a step earlier in the flow. Specifying a looping condition is only valid on the last step in the flow *unless* actions contains a Sankey rule that refers to the match ID of this step as one of the nodes. | | save_fields | array of [bitdrift_public.protobuf.workflow.v1.SaveField](bitdrift_public_protobuf_workflow_v1_SaveField.md "bitdrift_public.protobuf.workflow.v1.SaveField")
up to 100 items | Fields to save when this step is matched. These fields can be referred to by saved_field_id in a subsequent matcher. The ID of each SaveField must be unique within the flow. This is used for correlation matching in which flow completion is dependent on a particular set of field values being consistent across multiple steps in the flow. |

#### Example ```json { "exit_conditions": [ { "match_rule": { "generic_match": { "base_matcher": { "log_field": "field_name", "operator": "EQUAL", "string_value": "example" } }, "match_id": "_i1yUnHjKfmWpCaD5Tazo", "sample_rate": 100 } } ], "loop_match_id": "_i1yUnHjKfmWpCaD5Tazo", "match_rule": { "generic_match": { "base_matcher": { "log_field": "field_name", "operator": "EQUAL", "string_value": "example" } }, "match_id": "_i1yUnHjKfmWpCaD5Tazo", "sample_rate": 100 }, "save_fields": [ { "field_name": "", "id": "", "regex_capture": "" } ] } ``` # Step.ExitCondition **Source definition:** [`src/bitdrift/public/unary/workflows/v1/workflow.proto#L145-L165`]() A step exit condition. When an exit condition is met, flow execution resets to the start of the flow and will wait to match the initial step again.

| Field | Type | Description | |---|---|---| | match_rule | [bitdrift.public.unary.workflows.v1.MatchRule](bitdrift_public_unary_workflows_v1_MatchRule.md "bitdrift.public.unary.workflows.v1.MatchRule")(Only one of match_rule, or timeout can be set) | Exits on a match condition. | | timeout | [bitdrift.public.unary.workflows.v1.Step.ExitCondition.TimeoutExit](#bitdrift.public.unary.workflows.v1.Step.ExitCondition.TimeoutExit "bitdrift.public.unary.workflows.v1.Step.ExitCondition.TimeoutExit")(Only one of timeout, or match_rule can be set) | Exits on a timeout condition. |

| Field | Type | Description | |---|---|---| | id | string
between 1 and 100 chars | The ID of the timeout which can be referred to by actions. Must be unique within the workflow. | | timeout_rule | [bitdrift.public.unary.workflows.v1.Rule.RuleTimeout](bitdrift_public_unary_workflows_v1_Rule.md "bitdrift.public.unary.workflows.v1.Rule.RuleTimeout") | The timeout rule. |
