Set transaction with server-side API

Creates a new transaction for an end user of your app in Adapty and provides access level. The transaction created by this method will appear in your analytics and Event Feed and well as will be sent to all integrations.

This method is recommended over the Grant access level one.

important

If the product is not created in Adapty, the transaction will still be recorded in the Adapty database, meaning it will appear in analytics and be included in integration events.

However, the user will get only the default premium access level. So, if you want to control access more flexibly and assign different access levels, you must create products in Adapty.

Method and endpoint

POST https://api.adapty.io/api/v2/server-side-api/purchase/set/transaction/

Varies based on whether the purchase is a subscription or a one-time purchase.

Errors

400: Bad request

billing_issue_detected_at_date_comparison_error

A billing issue happens when there’s a problem during a subscription renewal attempt, so it always occurs after the transaction date (purchased_at).

To resolve this, make sure the billing issue date (billing_issue_detected_at) is later than the transaction date (purchased_at).

Body

Parameter	Type	Description
errors	Object	source: (string) Always billing_issue_detected_at errors: A description of the error.
error_code	String	Short error name. Always billing_issue_detected_at_date_comparison_error.
status_code	Integer	HTTP status. Always 400.

Response example

{
  "errors": [
    {
      "source": "billing_issue_detected_at",
      "errors": [
        "billing_issue_detected_at must be later than purchased_at."
      ]
    }
  ],
  "error_code": "billing_issue_detected_at_date_comparison_error",
  "status_code": 400
}

---

expires_date_error

A user can’t buy a subscription that has already expired. So, the expires_at date (when the subscription expires) should always be later than the purchased_at date (when the transaction occurred).

To fix this, check these dates and ensure that expires_at is after purchased_at.

Body

Parameter	Type	Description
errors	Object	source: (string) Always expires_at errors: A description of the error.
error_code	String	Short error name. Always expires_date_error.
status_code	Integer	HTTP status. Always 400.

Response example

{
  "errors": [
    {
      "source": "expires_at",
      "errors": [
        "expires_at must be later than purchased_at."
      ]
    }
  ],
  "error_code": "expires_date_error",
  "status_code": 400
}

---

family_share_price_error

The request failed because the is_family_shared parameter is set to true, meaning the access level is shared with a family member for free. However, the value parameter of the Price object isn’t set to zero.

If is_family_shared should be true, make sure to set the value parameter of the Price object to 0.

Body

Parameter	Type	Description
errors	Object	source: (string) Always is_family_shared errors: A description of the error.
error_code	String	Short error name. Always: family_share_price_error.
status_code	Integer	HTTP status. Always 400.

Response example

The profile is not found

{
  "errors": [
    {
      "source": "is_family_shared",
      "errors": [
        "If is_family_shared is true, price.value must be 0."
      ]
    }
  ],
  "error_code": "family_share_price_error",
  "status_code": 400
}

---

free_trial_price_error

The request failed because the offer_type parameter is set to free_trial, but the value parameter of the Price object isn’t set to zero.

Another possible reason is that the offer_id parameter was included but left null, even though it can’t be null. In this case, either provide a value for offer_id or remove the parameter entirely.

Body

Parameter	Type	Description
errors	Object	source: (string) Always offer.type errors: A description of the error.
error_code	String	Short error name. Always: free_trial_price_error.
status_code	Integer	HTTP status. Always 400.

Response example

The profile is not found

{
  "errors": [
    {
      "source": "offer_type",
      "errors": [
        "If offer_type is 'free_trial', price.value must be 0."
      ]
    }
  ],
  "error_code": "free_trial_price_error",
  "status_code": 400
}

---

grace_period_billing_error

The start of a grace period counts as a billing issue. So, if the grace period has started (indicated by the grace_period_expires_at parameter being filled in), its start date should be recorded in the billing_issue_detected_at parameter.

To fix this, either set the start of the grace period in billing_issue_detected_at or, if the grace period hasn’t started yet, remove the grace_period_expires_at parameter.

Body

Parameter	Type	Description
errors	Object	source: (string) Always grace_period_billing_error errors: A description of the error.
error_code	String	Short error name. Always grace_period_billing_error.
status_code	Integer	HTTP status. Always 400.

Response example

{
  "errors": [
    {
      "source": "grace_period_billing_error",
      "errors": [
        "If grace_period_expires_at is specified, billing_issue_detected_at must also be specified."
      ]
    }
  ],
  "error_code": "grace_period_billing_error",
  "status_code": 400
}

---

grace_period_expires_date_error

The request failed because the offer_type parameter is set to free_trial, but the value parameter of the Price object isn’t set to zero.

Another possible reason is that the offer_id parameter was included but left null, even though it can’t be null. In this case, either provide a value for offer_id or remove the parameter entirely.

Body

Parameter	Type	Description
errors	Object	source: (string) Always offer.type errors: A description of the error.
error_code	String	Short error name. Always: free_trial_price_error.
status_code	Integer	HTTP status. Always 400.

      ]
    }
  ],
  "error_code": "free_trial_price_error",
  "status_code": 400
}

---

missing_offer_id

The request failed because the offer_category parameter has a value other than introductory or offer_type but doesn’t include an offer_id. In this case, either provide an offer_id or remove the offer_category or offer_type from the request.

Another possible reason is that the offer_id parameter was added but left as null, even though it can’t be null. If that’s the case, either add a value for offer_id or remove the parameter entirely.

Body

Parameter	Type	Description
errors	Object	source: (string) Always offer.category errors: A description of the error.
error_code	String	Short error name. Possible value: missing_offer_id.
status_code	Integer	HTTP status. Always 400.

profile_does_not_exist

The request failed because the profile in the request header wasn’t found. Double-check that there are no typos in the profile_id or customer_user_id you entered in the request header, and make sure it’s for the correct app.

Body

Parameter	Type	Description

      ]
    }
  ],
  "error_code": "profile_does_not_exist",
  "status_code": 400
}

---

refund_date_error

The request failed because the purchase date (purchased_at) is earlier than or equal to the refund date (refunded_at). A refund always happens after a purchase, as it reverses the transaction.

To fix this, check the purchased_at and refunded_at parameters and make sure the refund date is later than the purchase date.

Body

Parameter	Type	Description
errors	Object	source: (string) Always refunded_at errors: A description of the error.
error_code	String	Short error name. Always refund_date_error.
status_code	Integer	HTTP status. Always 400.

Response example

      ]
    }
  ],
  "error_code": "refund_date_error",
  "status_code": 400
}

---

refund_fields_error

The request failed because it either includes cancellation_reason without a refunded_at date, or it has refunded_at without a cancellation_reason.

When a refund is set, both the refund date and reason need to be specified.

Body

Parameter	Type	Description
errors	Object	source: (string) Always refunded_at errors: A description of the error.
error_code	String	Short error name. Always refund_fields_error.
status_code	Integer	HTTP status. Always 400.

Response example

  "errors": [
    {
      "source": "refunded_at",
      "errors": [
        "refunded_at and cancellation_reason=refund must be specified together."
      ]
    }
  ],
  "error_code": "refund_fields_error",
  "status_code": 400
}

---

renew_status_changed_date_error

Renewal is a prolongation of a subscription. The user can cancel the subscription prolongation and then again prolong it. The time of both these actions is stored in the renew_status_changed_at parameter. And it can never happen earlier than the transaction itself.

To fix the issue, make sure the renew_status_changed_at is later than the time of the transaction (purchased_at).

Body

Parameter	Type	Description
errors	Object	source: (string) Always originally_purchased_at errors: A description of the error.
error_code	String	Short error name. Always originally_purchased_date_error.
status_code	Integer	HTTP status. Always 400.

Response example

{
  "errors": [
    {
      "source": "renew_status_changed_at",
      "errors": [
        "renew_status_changed_at must be later than purchased_at."
      ]
    }
  ],
  "error_code": "renew_status_changed_date_error",
  "status_code": 400
}

---

store_transaction_id_error

In the case of prolonged subscriptions, a chain of subscriptions is generated. The original transaction is the very first transaction in this chain and the chain is linked by it. Other transactions in the chain are prolongations. If the transaction is the very first purchase in the subscription chain, it can be its own original transaction.

Another case is a one-time purchase. It never creates chains as it cannot have prolongations. For it, the store_transaction_id is always the same as the store_original_transaction_id.

Your request failed because the store_transaction_id value for the One-Time Purchase object differs from its store_original_transaction_id . To fix the issue, either make them the same, or change the object - use Subscription instead of the One-Time Purchase.

Body

Parameter	Type	Description
errors	Object	source: (string) Always store_transaction_id errors: A description of the error.
error_code	String	Short error name. Always store_transaction_id_error.
status_code	Integer	HTTP status. Always 400.

Response example

{
  "errors": [
    {
      "source": "store_transaction_id",
      "errors": [
        "store_transaction_id must be equal to store_original_transaction_id for purchase."
      ]
    }
  ],
  "error_code": "store_transaction_id_error",
  "status_code": 400
}
