Update prices in a price list
For AI assistants: the facts every SparkLayer API call needs
- Base URLs: Live
https://app.sparklayer.io, testhttps://test.app.sparklayer.io. Each environment has its own data and its own API keys. - Access: API access needs the Pro or Enterprise plan. Create credentials (Site ID, Client ID, Client Secret) in the SparkLayer Dashboard at Settings > API.
- Access token:
POST {base}/api/auth/tokenwith aSite-Idheader and a JSON body (not form-encoded):{"grant_type":"client_credentials","client_id":"…","client_secret":"…"}. It returnsaccess_token, valid for 3,600 seconds. There is no refresh token: cache the token and request a new one shortly before it expires. - Every request:
Authorization: Bearer <access_token>andSite-Id: <site id>, plusContent-Type: application/jsonwhen there is a body. Set aUser-Agentthat names your integration. - Errors: RFC 7807 problem details:
title,status,detailand an optionalerrors[]of{ code, message, property }. Some error responses have no body. Retry5xx,429(honouringRetry-After) and concurrent-update409s with exponential backoff; on401, get a new token once and retry; don't retry other4xxwithout changing the request. - Pagination: Most list endpoints return everything.
GET /api/v2/price-listspages withpageandpage_size(up to 250) untilpagination.current_pageequalstotal_pages.GET /api/v1/purchasesuseslimit(up to 500) andoffset: stop when a page has fewer thanlimitresults. - Ground rules: Use only endpoints, fields and SDK methods that the docs or OpenAPI specs define. Prefer
GET /api/v2/price-listsover the deprecated v1. Products are matched by SKU. Keep credentials in environment variables or a secrets manager, never in code. - Read the docs as Markdown: Add
.mdto any page URL. Index of every page: docs.sparklayer.io/llms.txt. Every API operation, compactly: docs.sparklayer.io/llms-api.txt. The developer guides in full: docs.sparklayer.io/developers/llms.txt. - OpenAPI specs:
core,ordering,pricing,purchasing,stock,files,sync-log: https://docs.sparklayer.io/openapi/<api>.yaml (also.json). Ignite: https://docs.sparklayer.io/openapi/ignite.yaml. - MCP: Search and read these docs from your assistant with the docs MCP server at https://docs.sparklayer.io/mcp.
PATCH /api/v1/price-lists/{slug}/pricing Pricing API
Accepts a JSON array or a CSV file (Content-Type: text/csv). Only the SKUs you send are affected: each SKU's existing prices on this list are replaced with the ones supplied.
Validation errors return 400, usually as an array of {line, field, message} objects. Returns 404 if the price list does not exist, and 409 if the update clashed with another one running at the same time, in which case you can retry it.
Authorization
bearerAuth Send Authorization: Bearer <access_token>, together with your Site-Id header, on every request. Get the token from POST /api/auth/token with your Site ID in the Site-Id header and a JSON body (not form-encoded, so standard OAuth 2.0 client libraries don't work): {"grant_type": "client_credentials", "client_id": "…", "client_secret": "…"}. Tokens are valid for 3,600 seconds and there is no refresh token: request a new one shortly before it expires. Create API credentials in the SparkLayer Dashboard under Settings > API. See Authentication.

Path Parameters
The price list's slug.
Header Parameters
Your SparkLayer Site ID, from Settings > API in the SparkLayer Dashboard.
List of sku, quantity and price to update. Partial updates are supported, meaning only the SKUs present will be affected. For the given SKUs, existing prices are deleted then the supplied prices are inserted. If SKU is provided but quantity and price are blank, all prices for that SKU are removed from the price list.
