Payment tokens can be created outside of the create_payment_session API call. This is most commonly used to support existing subscription customers, allowing them to move their subscriptions to their HSA/FSA. Use create_payment_session with tokenize=True to create a subscription as part of a checkout flow, such as the first order in a subscription, or free trials.

Entering General Availability in Late October 2025

For early access, contact your Truemed sales engineer.

Overview

This endpoint supports creating a payment_token outside of the create_payment_session flow, and is commonly used to support giving the option to existing subscribers to pay with their HSA/FSA. This endpoint can also be used to “store a payment method with Truemed” inside of a user dashboard. Subscription free-trials are possible with this endpoint, though we recommend using create_payment_session for trials for consistency with the standard checkout experience.

This endpoint returns the ID of a new provision_token_request, NOT a new payment_token. The payment_token itself will be available upon receipt of the payment_token_updated webhook with the corresponding provision_token_request_id. In order to support backfills in the case of unforeseen downtime (a webhook that goes unacknowledged, or is missed), you can also query the status of the provision_token_request directly as outlined in our retrieve_provision_token_request docs.

This endpoint creates a Token Provision Request NOT a Payment Token

Partners only receive valid payment_tokens via the payment_token_updated webhook. A payment token can’t be issued until the user successfully completes the tele-health survey and/or enters payment information. A callback is used to indicate the customer has completed token setup with Truemed.

The diagram below outlines the customer flow when using this endpoint:

Create payment token

The merchant partner calls create_payment_token and receives a redirect_url.

Customer completes Truemed checkout

The customer is redirected to the redirect_url and completes the tele-health survey and enters payment information.

Customer returns to merchant

The customer is redirected to the success_url provided by the merchant during the initial call to create_payment_token.

Receive payment token

Truemed issues a payment_token_updated webhook including the newly provisioned payment_token. Customer email and name are included along with the metadata field to aid in linking to existing data in the partner’s backend.

The webhook/callback is invoked at the same time the user is being redirected to the success_url - we don’t guarantee that it will be called before the redirect.

Customer In The Flow

The customer must be in the flow when calling this endpoint, typically from within a subscription management dashboard.

Primary Use Cases for this Endpoint:

Supporting existing customers
- You may have existing subscriptions customers that want to move their subscription over to their HSA/FSA card. Providing a “use your HSA/FSA via Truemed” button within a subscription management dashboard powered by this endpoint allows you to do that.
Store payment method with Truemed
- Allow customers to add an HSA to their account for future use
Free-trial support (non preferred)
- Allowing customers to qualify for a given subscription and store their payment info for future use.
- ⚠️ We recommend using create_payment_session with tokenize=True for free trials as outlined in the main subscription guide to reflect the fact that the customer is “checking out”, though at no-cost.

Truemed does not handle your subscription

All subscription related fields here are to enhance the customer experience, you’ll need your own subscription management system.

Request Notes

success_url (Required): Where to redirect the user to after the customer successfully completes the tele-health survey and their payment method(s) have been stored.
- This is often used to display a confirmation screen, or similar
failure_url (Required): When the user opts to not complete the tele-health survey or selects “cancel” during the process, or when the user is ineligible to spend HSA/FSA funds on the items in the request.
- We attempt to recover from incorrect CVV, or other card detail errors by prompting the user for retry
customer_state (Optional): The 2-letter ISO 3166-2:US code for a region, without the US- prefix. For example, California should be provided as CA and Rhode Island as RI.
- If customer_state is provided, the state of residence question in the health survey will be prefilled with the full state name that corresponds to the ISO code.
metadata (Optional): Will be echoed back in the payment_token_updated webhook and detail endpoint if present.
- Important: This must be a string. If you want to include JSON, encode it as a string.
- Important: DO NOT INCLUDE sensitive information in this field.
use_iframe (Optional): Optional query parameter that can be used to modify the response’s redirect_url so it can be used and communicated with in an iframe.

iFrame Support

If use_iframe is set to true, redirect_url will be iframe-compatible. Partners can create an iframe and set the src to redirect_url and this will render Truemed’s survey and checkout flow in the iframe.

When using iframes, the flow completion is communicated via postMessage. The parent window should listen for messages from the iframe. The message will contain:

success: Returns true if checkout flow was successful on Truemed’s end, false if otherwise
redirectUrl: String that will be set to success_url from the original request body if success is true or set to failure_url if success is false.
- Only need to be used if redirect is desired or can handle success and failure differently

Response Notes

Success Case

HTTP Status: 200:

provision_token_request_id: A UUID that represents this creation request.
- This ID is returned along with the provisioned payment_token in the payment_token_updated webhook.
- You can query the status of this request using the retrieve_provision_token_request endpoint.
redirect_url: Contains a URI through which the customer can complete the payment_token.

Bad Request

HTTP Status: 400

If a field is missing or the request otherwise can’t be processed, we’ll return a 400 with the following fields:

error: Can be one of:
- MissingField: One of the required fields is not present in the request
- IdempotencyViolation: An idempotency_key was reused with different request parameters or the customer email specified in the request already has a payment token provisioned. Check to see if a payment_token_updated webhook was already received for this customer. To update, use the update_payment_token endpoint.
- WaitingForVerification: If the lmn verification process has started, you cannot attempt to call this endpoint again for the same customer email. If you receive this error, please wait for the payment_token_updated webhook and then use the update_payment_token endpoint.
- ServerError: There was an internal server error.
  - Requests can be retried as long as the idempotency_key is the same.
- ValidationError: There was an issue with the request. Check the message field for the exact issue.
message: Detailed string explaining the reason for the failure.
