Q: What is the advantage of using GraphQL over the HTTP Request node?

You can use the HTTP Request node to call GraphQL APIs, but the dedicated GraphQL node provides a cleaner interface. It has separate fields for the query, variables, and headers, which makes the configuration more readable. It also validates that you are sending a proper GraphQL request structure. For REST APIs, use HTTP Request. For GraphQL APIs, use the GraphQL node.

Q: Can I use the GraphQL node to write data, not just read it?

Yes. GraphQL mutations let you create, update, and delete data. You write a mutation query in the node, set the input variables from upstream node data, and the mutation executes against the API. This is how you would create a Shopify product, update a Contentful entry, or add a record in Hasura through n8n.

Q: How do I authenticate with a GraphQL API?

The node lets you set custom headers, which is where most GraphQL APIs expect authentication. Common patterns include Bearer tokens (Authorization: Bearer your-token), API keys in custom headers (X-API-Key: your-key), or Basic auth. You configure these as n8n credentials and the node includes them with every request.

Q: Can I pass dynamic variables to a GraphQL query?

Yes. You define variables in the GraphQL variables field as JSON, and you can reference values from previous nodes using n8n expressions. For example, you could pass a customer ID from a trigger node into a GraphQL query that fetches that customer's order history. This makes your queries reusable across different data inputs.

Q: Which platforms use GraphQL that I might need to connect to?

Shopify (Storefront and Admin APIs), GitHub, GitLab, Contentful, Strapi, Hasura, Fauna, Hygraph (formerly GraphCMS), and many modern SaaS platforms. If a service you use offers a GraphQL API, the n8n GraphQL node can connect to it. Check the API documentation for a /graphql endpoint.

Q: Can Osher help with GraphQL integration projects?

Yes. We build n8n workflows that connect to GraphQL APIs for e-commerce, content management, and custom application integrations. Whether you need to sync Shopify product data with your warehouse system or pull content from a headless CMS into your marketing tools, our n8n consulting team handles the query design and workflow implementation.

We can help you automate your business with GraphQL and hundreds of other systems to improve efficiency and productivity. Get in touch if you’d like to discuss implementing GraphQL.

About GraphQL

The GraphQL node in n8n lets you send queries and mutations to any GraphQL API directly from your automation workflows. Instead of making multiple REST API calls to assemble the data you need, a single GraphQL query can request exactly the fields you want from multiple related resources in one request.

GraphQL APIs are used by platforms like Shopify, GitHub, Contentful, Strapi, Hasura, and many modern SaaS products. If you are integrating with any of these services, the GraphQL node gives you precise control over what data you fetch. You write a GraphQL query, set your variables, and the node returns structured JSON with only the fields you asked for.

The node supports queries (read operations), mutations (write operations), and custom headers for authentication. You can pass Bearer tokens, API keys, or custom auth headers. Variables can be set dynamically from upstream nodes, so your GraphQL queries can be parameterised based on data flowing through the workflow.

At Osher, we use the GraphQL node for Shopify integrations, headless CMS connections, and any API that offers a GraphQL endpoint alongside or instead of REST. Our system integration team picks GraphQL over REST when the data requirements are complex and we need to reduce the number of API calls. If you are connecting to GraphQL-based services, our custom development team can build the queries and wire them into your workflows.

How it works

We work hand-in-hand with you to implement GraphQL

As GraphQL consultants we work with you hand in hand build more efficient and effective operations. Here’s how we will work with you to automate your business and integrate GraphQL with integrate and automate 800+ tools.

Step 1

Process Audit

We review the GraphQL APIs you need to connect to, documenting their schemas, authentication methods, and rate limits. We also assess your current data requirements to determine which queries and mutations will be needed and how they fit into your broader workflow architecture.

Step 2

Identify Automation Opportunities

We identify where GraphQL queries can replace manual data lookups, multiple REST API calls, or copy-paste processes. For each opportunity, we evaluate whether a GraphQL query can fetch all required data in a single request and calculate the efficiency gain compared to the current approach.

Step 3

Design Workflows

We write the GraphQL queries and mutations, design the variable parameterisation, and plan the workflow architecture. For complex integrations, we may design multiple queries that run in sequence, with data from one feeding into variables for the next.

Step 4

Implementation

We configure the GraphQL node with the endpoint URL, authentication credentials, queries, and variables. We connect it to upstream data sources and downstream processing nodes. We test each query against the live API with sample data to verify correct results.

Step 5

Quality Assurance Review

We test queries with various input combinations, verify that mutations produce the expected changes, and check error handling for invalid inputs, rate limit responses, and authentication failures. We also test query performance to ensure response times are acceptable for your workflow timing requirements.

Step 6

Support and Maintenance

We monitor for GraphQL schema changes from the APIs you connect to (breaking changes, deprecated fields, new required arguments) and update your queries accordingly. We also optimise query performance over time and adjust workflows when your data requirements change.
