REST API

LoyJoy offers a REST API for programmatically accessing process definitions, home views, catalogs, articles, notifications and variables.

caution

The API is in beta and might change in the future.

Authorization API

All of the following endpoints require authorization with a bearer access token. Such an access token can be retrieved at cloud.loyjoy.com in the tenant settings at tab API. Please note that the access token is associated to the user account and tenant it has been generated for. Thus removing an user from a tenant invalidates the access token.

Process Definitions API

List All Process Definitions as JSON

Returns a JSON list of all process definitions in the tenant.

curl -X GET "https://app-stable.loyjoy.com/api/process-definition" \
-H "Authorization: Bearer <BEARER_TOKEN>" \
-H "Content-Type: application/json"

Get a Process Definition as JSON

Returns a JSON representation of the process definition in the tenant.

curl -X GET "https://app-stable.loyjoy.com/api/process-definition/<PROCESS_DEFINITION_ID>" \
-H "Authorization: Bearer <BEARER_TOKEN>" \
-H "Content-Type: application/json"

Get a Process Definition as XML

Returns a XML representation of the process definition in the tenant. This is the XML serialization as executed by the LoyJoy runtime engine. Please note that the XML schema might change in the future with further development of LoyJoy functionality, i.e. the XML schema does not constitute an API.

curl -X GET "https://app-stable.loyjoy.com/api/process-definition/xml/<PROCESS_DEFINITION_ID>" \
-H "Authorization: Bearer <BEARER_TOKEN>" \
-H "Content-Type: application/xml"

Start a Process Definition

Starts a process definition programmatically. This call optionally can ingest variables, and then returns the resulting variables. The process instance will halt if the process definition expects user input. E.g. if the process definition contains a Proceed process module it will halt on the proceed question. Halting can be prevented by using only process modules that do not require user interaction.

curl -X POST "https://app-stable.loyjoy.com/api/process-definition/start/<PROCESS_DEFINITION_ID>" \
-H "Authorization: Bearer <BEARER_TOKEN>" \
-H "Content-Type: application/json" \
-d '{ "variables": { "some_var": { "value": "some_value" } }, "withVariablesInReturn": true }'

Sources API for GPT knowledge modules

These endpoints provide read and write access to sources used by the GPT knowledge module. They allow you to add sources such as websites or files to the knowledge base, retrieve them, and delete them. Sources can be added via publicly available URLs or by uploading files. If you want to upload a large number of files programmatically, there exists an examplary script.

Additionally, the API also allows you to update the sources according to a schedule or on demand. To achieve this, you can simply delete some or all of your sources and then re-add them. This will trigger a re-crawl of the source.

List All Sources as JSON

Returns a JSON list of all knowledge sources in the tenant.

-H "Authorization: Bearer <BEARER_TOKEN>" \

curl -X DELETE "https://app-stable.loyjoy.com/api/sources" \
-H "Authorization: Bearer <BEARER_TOKEN>" \
-H "Content-Type: application/json"

Each source takes approximately 500ms to be deleted. If you want to delete several hundred or thousand of sources, the API call might time out on the load balancer. However, in the background the deletion should continue. In case of a timeout, please do not retry directly after timeout, but instead wait for several minutes until retry. You can check the status of the deletion by calling the GET /sources endpoint and counting the resulting items.
