API error with FlutterFlow
I have a WorFlow (“Stripe Payment Checkout Link Creator”) that works manually in BuildShip 2.0. The input is in the format:
[{
"price": (x) Price ID,
"quantity": (x) Quantity
}]
In FlutterFlow I call the API with the following JSON file:
{
"PriceID": "<varpriceId>",
"Quantity": <varquantity>
}
I've tried other variations:
{
"PriceId": "<varpriceId>",
"quantity": <varquantity>
}
{
"Price ID": "<varpriceId>",
"Quantity": <varquantity>
}
It's always a mistake:
"type": "StripeInvalidRequestError",
"raw": {
"message": "The
line_items parameter...
Has anyone experienced this problem and been able to solve it? Could you post the solution here?
Thank you.Solution:Jump to solution
I did it simply by recreating a new, similar workflow. I conclude that I made a mistake in changing the original template.

The error you are encountering, "The
line_items parameter," suggests that there might be a mismatch in how the line_items are structured in your API calls compared to what Stripe expects.
The line_items parameter in Stripe generally requires a specific structure. It's crucial to ensure that the JSON body you send matches the expected format for creating a Checkout Session. Here's a generalized example of how the line_items should be structured:
Based on this format, make sure your API call aligns with this structure. Your FlutterFlow JSON call should reflect this structure, with the price key exactly matching your Price ID from Stripe and quantity being a number.
If you haven't done so already, you can use the Stripe dashboard or the API documentation to verify that your Price ID is correct and exists in your Stripe account. Also, ensure that you have included it in the line_items properly.
If you continue to experience issues, it may be beneficial to check the API documentation for any additional required fields specific to your setup or validate your JSON format and keys within the context of the BuildShip and Stripe integration guidance【4:7†source】.

When calling the API in FlutterFlow, the body displayed is:
{
"price": "price_1QN9AjJEAEYO5vN4ikHJTe3i",
"quantity": 1
}
Log BuildShip:
Error: The
line_items parameter is required in payment mode.
Logs Stripe:
{
"error": {
"message": "The line_items parameter is required in payment mode.",
"request_logurl": "https://dashboard.stripe.com/test/logs/req**",
"type": "invalid_request_error"
}
}
Post Body:
{
"mode": "payment",
"payment_method_types": {
"0": "card"
},
"success_url": "https://aur25w.buildship.run/checkout-message-******"

It should be:
{
"line_items": {
"0": {
"price": "price_1QN9AjJEAEYO5vN**",
"quantity": "1"
}
},
"mode": "payment",
"payment_method_types": {

I can't export the API, it seems that this is only possible with paid plans. I called BuildShip Support asking if I could export the API if I bought credits (U$10.00) before signing up for a plan. I'm waiting for a reply, but if anyone knows about this, please let me know.
