Notes

  • You can check and copy the launching URL to clipboard in the property screen
  • The parameter and IP filtering details can be checked in the other page after clicking the [URL, Reception Parameter] button in the property screen
  • The value of API key (key) can be set arbitrarily with halfwidth alphanumeric characters, at most 100 in length
    • Even though it is possible to leave the API key blank, please set the API key to tighten the security
  • If the incoming HTTP request data does not meet the Data Item constraints, such as required settings and minimum/maximum character length, the process will not start
  • There is a possibility that Process not to be started automatically due to the limit on the number of startups on the entire Workflow platform
  • There is a possibility that Process not to be started automatically due to the size limit of the data that can be received
  • Communication from the external network is not permitted by default on the Workflow platform
    • To allow communication from an external network, change the settings in [IP Address Filtering] < [System Settings] (M312: System Administrator Authority Required)
    • It is possible to set an IP address filter for each trigger URL
  • If the incoming request has a “Questetra-Debug: true” header, it will start as a debug process
    • If the caller is a debug process, or the header has been explicitly added
    • Human Task handling in the debugging Process is assigned to the final editor of the App
  • When a Process is started by calling this event from a [Throwing Message Intermediate Event (HTTP)], etc. within the same platform, a parent-child relationship is established with the started Process as a child and the calling Process as a parent
    • The child Process has the ID of the parent Process as Process attribute information
  • [Service Task (Start Child Process)] is an item for sending an HTTP request to this Start Event to start a child Process
    • When a [Message Start Event (HTTP)] is set, the corresponding [Service Task (Start Child Process)] will appear in the modeler palette one by one
