PurchasePlus API

A RESTful API for the entire PurchasePlus platform.

Resource-oriented URLs, form-encoded request bodies, JSON-encoded responses, standard HTTP response codes, and a mix of standard and extended action verbs. Four separate modules cover purchasing, invoicing, inventory, and recipes.

4 Modules

Four modules. One platform.

The API is broken into 4 separate modules representing functional areas within PurchasePlus. Each module has its own SwaggerHub reference documentation. Your application may need some or all, depending on your requirements.

SwaggerHub paths above are gradually replacing legacy app.swaggerhub.com references. Treat any remaining app.swaggerhub.com docs as insufficiently maintained.

Technical Reference

Everything you need to start building.

Authentication Token-based

The PurchasePlus API uses token-based authentication. Make a sign-in request with your account email and password. The response headers contain Access-token, Client, and Uid, which must be passed on every subsequent request.

To Sign In

# Sign in curl -D - "https://api.purchaseplus.com/access/api/auth/sign_in" \ -H "Accept: application/vnd.mbapi.v2+json" \ -d "email=your.name@yourbusiness.com&password=yourpassword"

If the request is successful, the response body contains your user account details. The headers contain the three values you'll need on every later call:

  • Access-tokenXxhhFMpq-RQxBJb_LhuCNO
  • Client4eWvqjwfS8KFaNG89dD4Tj
  • Uidyour.name@yourorganisation.com

Subsequent Requests

curl "https://api.purchaseplus.com/purchasing/api/purchaser/:id/invoices" \ -H "Accept: application/vnd.mbapi.v2+json" \ -H "Access-token: XxhhFMpq-RQxBJb_LhuCNO" \ -H "Client: 4eWvqjwfS8KFaNG89dD4Tj" \ -H "Uid: your.name@yourorganisation.com"

Authorisation RBAC via Personas

Once your user is authenticated, the resources you can access and what you can do with them is controlled by the authorisation system. This is currently based on the Personas your user has been assigned, and can only be maintained through the PurchasePlus user interface. To obtain additional authorisation, please speak with an administrator at your Organisation, or contact our customer success team.

Errors

The PurchasePlus API uses standard HTTP response codes to indicate whether your request was successful or whether there was an issue.

  • 200OKRequest was successful
  • 400Bad RequestPossibly missing data
  • 401UnauthorisedInvalid Access-token, Client, or Uid
  • 403ForbiddenPersona lacks permission
  • 404Not FoundResource does not exist; check the URL or id
  • 406Not AcceptableRequired attributes missing
  • 409ConflictResource may have been updated since you retrieved it
  • 429Too Many RequestsLimit is 5 per second
  • 500Server ErrorContact support if it persists

Pagination page parameter

For requests that return multiple records, you may need to make multiple requests to retrieve all results. Pass the page parameter with the page number you wish to request.

curl "https://api.purchaseplus.com/purchasing/api/purchaser/:id/invoices" \ -H "Accept: application/vnd.mbapi.v2+json" \ -H "Access-token: ..." \ -H "Client: ..." \ -H "Uid: ..." \ -d "page=2"

Filtering filter[field_predicate]=value

For requests that return multiple records, you can filter results using filter parameters. Example, returning invoices with the string "INV":

curl "https://api.purchaseplus.com/purchasing/api/purchaser/:id/invoices" \ -H "Accept: application/vnd.mbapi.v2+json" \ -H "Access-token: ..." \ -H "Client: ..." \ -H "Uid: ..." \ -d "filter[invoice_number_cont]=INV"

Available predicates:

Request IDs PP-Request-Id

Each request you make to our API is logged and assigned a request id, returned in the PP-Request-Id response header. Use this id when contacting support about a specific request.

Versioning v2.0

The PurchasePlus API is currently on version 2.0. Provide the version on every request via the Accept header. If omitted, the system falls back to the deprecated v1.0 API (v1.0 reference here).

curl "https://api.purchaseplus.com/access/api/auth/sign_in" \ -H "Accept: application/vnd.mbapi.v2+json"

Refer to the Change Notes below for any breaking version changes, new endpoints, or new and deleted fields.

Idempotent Requests Idempotency-Key

The PurchasePlus API can optionally support idempotency to prevent the same transaction occurring multiple times. Provide the case-sensitive Idempotency-Key header on a request, with a UUID as its value.

If you make a request with the same Idempotency-Key twice, you receive the cached version of the original successful result. Only provide an Idempotency-Key for POST or PATCH requests, never GET or DELETE.

curl "https://api.purchaseplus.com/purchasing/api/purchaser/:id/invoices" \ -H "Accept: application/vnd.mbapi.v2+json" \ -H "Idempotency-Key: ca2a1871-82a2-496f-a2d2-3525d69426c3" \ -H "Access-token: XxhhFMpq-RQxBJb_LhuCNO" \ -H "Client: 4eWvqjwfS8KFaNG89dD4Tj" \ -H "Uid: your.name@yourorganisation.com"

Rate Limiting 5 rps / IP

The PurchasePlus API is rate limited to protect all users from load issues. If your application reaches the limit you will see HTTP 429 on requests. The current limit is 5 requests per second per IP address. Contact our team if this is too low for your requirements.

Handle these errors gracefully by monitoring for 429s and implementing a retry mechanism with back-off.
