Injected History

Below is a detailed look at injected history.

    "traversalId": Guid,
    "assetId": int,
    "answerId": int,
    "value": "string",
    "injectedHistoryType": Enum,
    "isAnswered": bool

TraversalId : Your unique traversal Identifier. Nullable

AssetId : Identifier of the asset, i.e. Question Id. Required

AnswerId : Identifier of the Answer. Required

Value : The value of answer. Only used for answers that were of type Text, Date, or Number. Nullable

InjectedHistoryType : An enum that takes either PreAnswer or PrePopulate.
PreAnswer tells the API to automatically answer the question so it will not be shown on the UI. PrePopulate returns the question to the UI, but the given answers will be already set. These answers are changable.

IsAnswered : Tells us which answer of a question was selected. If the asnwer is of type Text, Date, or Number you still need to set the isAnswered to true.

When starting a product like Online triage (aka Symptom Assessment) it is possible to push data into your traversal that could affect the questions and answers you see. Taking the example from the quickstart guide, if we wanted to skip the question asking who you're answering for, you would push the data for that question into your first API call.

The below call will now skip the first question, immediately moving to the second question.

curl ".../api/v1/{tenantId}/Traversals" \
  -X "POST" \
  -H "Authorization: Bearer ACCESS_TOKEN" \
  -H "Content-Type: application/json" -d '{
    "shortCode": "XYZ",
    "injectedHistory": [{
	"assetId": 13045,
	"answerId": 7527,
	"injectedHistoryType": "PreAnswer",
	"isAnswered": true
	"assetId": 13045,
	"answerId": 7528,
	"injectedHistoryType": "PreAnswer",
	"isAnswered": false

You could easily do this for any question in a product, assuming you knew all the pertinent Ids and values. But they do need to be injected at the start of a traversal, when it's created.
