Create a Collection from Local File

This flow imports an OpenAPI / Swagger specification by uploading a file directly from your local machine. It supports .json, .yaml, and .yml formats.

This is the recommended method when you have a local copy of the spec — for example, a file generated by your build pipeline, exported from Postman or Stoplight, or maintained in your version control repository — and do not need to fetch it from a live endpoint.

Step 1 — Import Source: From Local File

Click + New Collection from the API Collections Summary. The wizard opens on Step 1.

Step 1 — Import Source (From Local File, empty)

Select From Local File. A file picker area appears below:

Control Description
Pick Swagger File Opens your browser's file picker. Accepted formats: .json, .yaml, .yml.
Accepted formats .json · .yaml · .yml

Click Pick Swagger File and select your OpenAPI spec file. Once selected, the file is parsed immediately client-side and a confirmation row appears showing:

  • File name and size (e.g. banking-enriched.swagger.yaml · 37.5 KB)
  • Validation result — a green confirmation showing the detected API name and path count (e.g. Digital Banking Platform API — 8 paths)

Step 1 — Import Source (From Local File, file selected)

Invalid files are rejected

If the file is not a valid OpenAPI / Swagger document, an error is shown instead of the green confirmation. Correct the file and re-upload before proceeding.

Click Next to proceed. The Next button is disabled until a valid file has been successfully parsed.

Step 2 — Explore Spec

BizMetry renders an interactive preview of the imported spec.

Step 2 — Explore Spec (From Local File)

The preview shows:

  • API name and version badges — extracted from info.title and info.version (e.g. Digital Banking Platform API · 2.0.0 · OAS 3.0).
  • Description — the info.description field from the spec, rendered as formatted text.
  • Server selector — if the spec defines multiple servers, a dropdown allows selecting the active base URL (e.g. https://api.banking.bizmetry.io/v2 - Production).
  • Tags and path groups — operations grouped by their OpenAPI tag with a group summary. Each group is expandable.
  • Endpoint rows — each row shows the HTTP method badge (GET, POST, etc.), the path, the operation summary, and a lock icon if the endpoint requires authentication. Click the chevron (▾) to expand and inspect the full operation detail.

Review the spec carefully to confirm it is the correct contract before saving. Click Next to continue. Click Back to return to Step 1 and upload a different file.

Step 3 — Details

Set the collection name and description before saving.

Step 3 — Details (From Local File)

A summary card at the top confirms what was imported:

API name · version · N paths · From Local File

Below it, two read-only fields and two editable fields:

Field Editable Description
Version Extracted from info.version in the spec. Not editable — defined by the spec itself.
Tags Tag groups defined in the spec (e.g. Customers, Accounts, Loans, Transactions, Cards, Branches). Extracted automatically — not editable.
Collection Name Display name for this collection in BizMetry (max 80 characters). Pre-filled from the spec's info.title.
Description Free-text description of this collection's purpose. Pre-filled from the spec's info.description.

Click Create Collection to save the collection in DRAFT state. Click Back to return to Step 2. Click Cancel to discard.

Step 3 — Review before creating (From Local File)

After Creation

The collection is created in DRAFT state and appears in the API Collections Summary. From there you can:

  • Edit the name and description (while in DRAFT).
  • Submit it for review when it is ready.
  • Proceed through the full lifecycle to publish it and make it available for Biz Event mappings.
