Beyond a one-time import, Postchi supports source syncing: you link a URL to a live spec, and Postchi checks for updates and merges new or changed operations into your project while preserving any edits you’ve made. With an open api spec you also get enhanced linting, requests are chcked against the spec and provide auto complete for values and show errors if the request does not conform to the spec.

​
Add an OpenAPI source

1

Open Imports

From the file menu select Import then select Live Source
2

Provide the spec URL

Enter the URL of your OpenAPI spec. For example:
Postchi accepts both JSON and YAML specs.
3

Choose a folder name (coming soon)

Enter a name for the collection folder Postchi will create. This becomes the top-level folder under your requests/ directory.
4

Configure auth (optional)

If the spec URL requires authentication — for example, a private GitLab repository — provide a personal access token. currently postchi supports Github and Gitlab personal access tokens.
5

Click Fetch Spec

Postchi downloads the spec, and shows the name and version of the spec.
6

Import

Postchi downloads the spec, generates request files
7

Configure

After import click configure to open the settings for this source. Set a base url and configure the authentication methods that were discovered from the spec file.

​
What gets generated

Postchi groups operations by their first OpenAPI tag. Each tag becomes a subfolder, and each operation becomes a .chttp request file inside it. Operations with no tags are placed directly in the root collection folder. File naming: the request file name comes from the operation’s summary field. If no summary is set, Postchi falls back to the operationId, then to METHOD /path.
Open api spec paths are relative make sure to set a base url in the root source folder

​
Syncing updates

At startup postchi checks for changes in the remote source:
  1. Postchi fetches the latest spec and compares it to your local request files.
  2. A diff view shows added, modified, and removed operations.
  3. Review the changes and click Apply Changes to update your files.
If you’ve edited a request file — changed a header value, filled in a query parameter, or customized the body — Postchi preserves your changes when applying upstream updates.
