SDK Reference¶

The SDK Reference covers everything you need to build, configure, and operate durable functions.

The core building blocks for constructing durable workflows:

• Step Execute and checkpoint a unit of work
• Wait Pause execution for a duration
• Wait for Condition Pause until an external condition is met
• Callback Resume execution via an external signal
• Invoke Invoke another durable function
• Parallel Execute multiple operations concurrently
• Map Apply an operation across a collection
• Child Context Scope a sub-workflow within a parent

Error Handling¶

• Errors Exception types and error response formats
• Retries Configuring retry behavior for steps

State¶

• Serialization How state is serialized between checkpoints

Observability¶

• Logging Structured logging within durable functions

Configuration¶
