@Marvin How do I use the Prefect 2 REST API to get a list of users that have deployed a flow?

It seems that directly obtaining a list of users who have deployed a flow via the Prefect 2 REST API is not clearly documented. However, here are some steps you could take to piece together this information: 1. Create a Deployment: When you create a deployment in Prefect 2.0, as shown in the Deployment guide, you do so by calling a method on the flow object. The deployment contains metadata, which may include information about who created it if such metadata is logged or captured in your system. 2. Use the Prefect UI: You might be able to see who deployed a flow through the Prefect UI, as deployments are linked to user accounts. 3. Check the Runtime Context: By examining the runtime context guide, you might find a way to extract metadata including user information at runtime, though this is not exactly the REST API approach. 4. Interact with the Prefect API: As the migration guide indicates, Prefect moved from GraphQL to a REST API in Prefect 2.0. However, it does not provide a clear instruction on REST API endpoints to get a list of users who deployed a flow. 5. Explore API through Swagger: The Prefect 2.0 API could provide Swagger/OpenAPI documentation with a full list of available endpoints. You can usually find this by accessing the

/docs

or

/_/api/docs

endpoint on the running Prefect server. In the absence of specific documentation on obtaining a list of users who deployed a flow directly from the REST API, you might need to explore the API manually or reach out to Prefect support for more detailed guidance. Lastly, if Prefect emits logs upon deployment that include the deployer's identity, you may be able to query those logs to compile the list of users. Keep in mind that this is based on my most recent understanding, and it is possible that Prefect has updated their documentation or features since my last update in April 2023.

@Marvin Is there a route in the rest api I can use to get a list of all deployments?

According to the Prefect 2.0 documentation, Deployments are server-side representations of flows that include crucial metadata for remote orchestration. However, the documentation excerpts provided do not give a specific REST API route for listing all deployments. To list all deployments via the Prefect 2.0 REST API, you will need to access the API endpoint that corresponds to deployments. While the documentation excerpts do not specify the endpoint, generally, such endpoints are structured in a RESTful manner, for example:

GET /api/deployments/

To confirm the exact endpoint and how to use it, you should access the Swagger/OpenAPI documentation that comes with Prefect server by navigating to the

/docs

or

/_/api/docs

path in your web browser while the Prefect server is running. This will show you the available endpoints, methods, and how to use them, including any additional parameters you might need to provide to get the list of all deployments.

@Marvin How do i use the graphql prefect api?

It looks like the information provided doesn't explicitly cover how to use the GraphQL API with Prefect. However, based on previous knowledge, here's a general approach to using GraphQL with Prefect: 1. Set the API URL: Ensure that your Prefect client is configured to communicate with the Prefect server or Prefect Cloud instance. You might need to set the

PREFECT_API_URL

environment variable or configure this using the Prefect client in your code. 2. Write a GraphQL query or mutation: Define the query or mutation according to your needs. Prefect's GraphQL API uses standard GraphQL syntax. 3. Execute the GraphQL query: With your client set up, you can post the query to the Prefect server. If you are using Prefect's Python client, it should have methods built-in for making GraphQL requests. 4. Handle the response: Parse the response you get back from the server. This will typically be in JSON format, including a

data

field with your requested information or

errors

field if something went wrong. While the specific endpoints and details for Prefect's GraphQL API are not provided in these excerpts, you can usually find this information in the Prefect Cloud user interface or API documentation, where the GraphQL Playground or interactive documentation is hosted. For Prefect Cloud, interactive documentation may be available at

<https://app.prefect.cloud/api/docs>

. To get the most specific and accurate information, you should refer to the official Prefect documentation or contact Prefect support for guidance on using their GraphQL API.
