Sending data to PersonaInquiries (Client-side integrations)Integration MethodsHosted Flow

Parameters

Query string parameters can be passed to customize the behavior of the hosted flow.

There are two main ways to use the hosted flow: creating new inquiries, and resuming existing inquiries. If you have an inquiry-id available (e.g. from creating an inquiry via API), please see Resuming existing inquiries.

Special characters in URL parameters

Be sure to escape your values if you are passing non-alphanumeric characters in your parameters. For example, values including whitespace or symbols like + and & need to be escaped. In JavaScript, this can be done with encodeURIComponent.

For example, if your redirect-uri itself contains a query string, & should be replaced with %26.

Creating new inquiries

The most common way to set up the hosted flow is to specify an inquiry template ID (inquiry-template-id). This will create a new inquiry every time the link is accessed.

Persona recommends connecting new inquiries to an account. To connect the inquiry to an account, specify either referenceId or accountId. You cannot specify both.

ParameterRequirementDescription
inquiry-template-id``inquiry-template-version-id``template-idRequiredThis template ID corresponds to a pre-set configuration and determines how the flow is customized. See Inquiry Templates.
environment-idThe Persona API environment on which to create inquiries. See Environments.
reference-idYou can generate and provide a unique ID which we will associate with the inquiry. Oftentimes this will be the unique user identifier from your system. A new account will be created if no account with the given reference ID exists. Inquiries with the same reference ID will be associated with the same account. See Reference IDs.
account-idID of an existing account to associate newly created inquiries with. If account-id is passed, passing either reference-id or account-type-id will result in an error. See Accounts.
account-type-idID of the account type to use if creating a new account for the inquiry. If omitted, the default account type associated with the current environment will be used. account-type-id will be ignored if a new account is not created (for example, if passed with a reference-id that does not correspond with an existing account).
fieldsProvide an object to set inquiry field values. Each attribute in the object is optional. This will also prefill form inputs corresponding to the field in the flow. See Fields.

Access inquiry created via API or resuming existing inquiries

If you have pre-created an inquiry via API or you are looking to resume an existing inquiry instead of creating a new one, use the inquiryId parameter. Do not pass a templateId or templateVersionId when resuming the inquiry.

If the inquiry already has submitted verifications, you need to specify a session-token as well. You can generate a session token with the /api/v1/inquiries/[inquiry-id]/resume endpoint.

ParameterRequiredDescription
inquiry-idRequiredSpecify an inquiry ID to resume an existing inquiry. If the inquiry has a pending status, then a sessionToken from the server-side API is required.
session-tokenWhen resuming an inquiry with a pending status, you must also generate a session token from the server-side API. See Inquiry Sessions.

Other parameters

These parameters are not related to creating or resuming inquiries, and can always be specified.

ParameterRequiredDescription
languageSpecify a supported language to localize the flow. Language will be inferred from browser settings by default. See Languages.
redirect-uriWhen the user successfully verifies their identity, we redirect back to this URI. The callback should expect a GET parameter named inquiry-id that references the completed inquiry. If no redirect-uri is specified, then the success page shown to users will not have a continue button. See Security for instructions on configuring a redirect URI allowlist. See Redirecting On Complete.
theme-set-idBeta feature. Pass a specific theme set to be used.

Deprecated parameters

Deprecated attributes

Deprecated attributes are planned to be removed or replaced in the future. They will continue to work in the immediate future.

ParameterDescription
environmentDeprecated. Use environment-id instead. The Persona API environment on which to create inquiries. For sandbox and production, use sandbox and production respectively.
prefillDeprecated. Use fields instead. Provide an object to prefill form inputs in the flow. Each attribute in the object is optional. See Prefill documentation.
routing-countryDeprecated. No longer necessary. Pass a specific country to route requests to. Persona now automatically routes requests to the best location, so this parameter is no longer needed.
theme-idDeprecated. Legacy templates only. Not available for Dynamic Flow. Pass a specific theme to be used.
