Developers please use (stage version of Bimplus API) and (stage version of Shop/Portal) for testing purposes. The production version of the portal is located under and the base url of the API is different for the production version.

Postman examples

Please install Postman and import attached postman collections
BimPlus.postman_collection.json

postman_globals.json
Production.postman_environment.json
Stage.postman_environment.json

if you don't know how it works show this video
Set Postman authenication direct to OIDC server, avoiding authentication request on start.
Postman supports OpenID authentication and can receive tokens directly from OIDC server.
Open request group (or even down to single request), select Authorization page, set authorisation type 'OAuth 2.0' and configure OIDC BIm+ server.

Then create Configure new token. Take server names from answer on discovery URL.
Preferrably use variables to specify different servers for different environments.

Click "Get New Access Token". Token should be loaded in token field.
Set "Auto-refresh Token" above to ON.
Example for Ifc Import, creation of new revisions and final revision compare
Example for creating Modeldata
by using Geometry templates controller, objects controller and geometry types
install additional postman collection

Some mp4, which shows usage of geometry templates, csg and mesh data
Example for Attribute management and PSet definitions
