Access to API

Access to API
Get API credentials and open the API reference for authentication, signing, and endpoint details

Get credentials in the Hub, then use the get started API v1 or get started API v2 reference for authentication, request signing, errors, base URLs, and rate limits.

Solidgate APIs are available in two versions.

Solidgate API v1 powers card and alternative payments, checkout solutions, Billing 1.0 subscriptions, products, prices, reports, and risk tools. Solidgate API v2 is recommended for new integrations that use the unified host, Bearer authentication, and scoped API keys. Coverage continues to expand across platform and product domains.
API v1 HMAC signature

Authenticate with the channel Public and Secret keys and an HMAC-SHA512 signature on every request. Domain-specific hosts serve payments, subscriptions, checkout, reports, and risks.

Includes

Card payments Alternative payments Payment Page and Link Products and prices Billing 1.0 subscriptions Reports Fraud prevention Webhooks and files
API v2 Bearer token

Authenticate with a Bearer token. Keys can apply to the whole account or selected channels, with fine-grained permissions. All operations use one host and a consistent resource/action path pattern.

Includes

Customers Invoices Payment instruments Subscriptions API keys and channels Webhooks Antifraud lists Routing and reports

Overview

Full request and response contracts remain in the Solidgate API reference.

API v1API v2
Authenticationmerchant and signature headers.
HMAC-SHA512 over publicKey + body + publicKey.
Authorization: Bearer with the API secret.
No request signature.
API keysChannel keys with prefixes api_pk_ / api_sk_.Account or channel-bound keys with prefixes akey_ / asec_.
Scopes by channel and permission. Zero-downtime rotation.
Host and pathMultiple hosts, for example pay.solidgate.com, gate.solidgate.com, subscriptions.solidgate.com. Action after /api/v1/.Single host https://api.solidgate.com/v2. Pattern /{resources}/{action}.
HTTP methodDepends on the operation (POST, GET, and others).POST for all operations.
ErrorsNested error object with numeric-style codes, for example 3.02.Flat envelope with named codes, for example PERMISSION_DENIED, optional context, and a request-id header.
WebhooksValidate with webhook Public and Secret keys using the same HMAC-SHA512 model as API requests.Manage endpoints via API v2. Validate with the endpoint secret using HMAC-SHA256 in the signature header.
Best fitPayment processing, Payment Page and Link, products and prices, Billing 1.0, classic reports and risk APIs.New integrations on the unified v2 host, scoped API keys, platform management, and expanding product domains in the API Reference.

Retrieve your credentials

To call the Solidgate API, even in the sandbox, you need credentials from the Solidgate Hub .

  • Solidgate API v1
    Public and Secret keys from Developers > channel details. Prefixes api_pk_ / api_sk_. Webhook keys use wh_pk_ / wh_sk_.
  • Solidgate API v2
    Create keys under Developers > API v2 > API keys. Prefixes akey_ / asec_. Restrict by channel when needed.
To generate API keys

  1. Go to Developers.
  2. Select the API version.
    • For API v1: select the channel you need, then on the Channel details page find the API keys.
    • For API v2: go to Keys, click on Create API key, name your keys and optionally select a channel or multiple channels, then click on Create.
  3. Copy your API key.
Never expose Secret keys in client-side code or public repositories. Use them only in secure server-side environments.

Generate signature

Request signing applies to Solidgate API v1 only. Build the HMAC-SHA512 generate signature API v1 and send it with the merchant and signature headers.

Solidgate API v2 uses Bearer authentication and does not require a request signature.

API logs

API logs capture request and response records in the Hub. Use them to troubleshoot issues, monitor traffic, and investigate unexpected API usage.

Search request and response body content directly on the API logs page. Combine body search with filters for status code, method, host, and date range to isolate a specific entry.

To find and view API v1 log entries

  1. Go to Developers > API logs.
  2. Enter a search query for terms or phrases in the request and response bodies.
    • Use single terms, phrases, wildcards, or boolean logic (AND, OR, exclude with -).
    • Optionally narrow results with Status, Method, Host, and date range filters.
  3. Find the log entry you need and click on it.
  4. View log entry details, including Status, Method, Path, Host, IP address, and Date (UTC).
  5. Expand Request body and Response body to see the JSON payloads sent and received.

Body search always covers request and response together. It does not support separate request-only or response-only search, or regular expressions. The query length is limited to 1,000 characters. Colons and other special characters are treated as plain text, not operators.
