Dear Neo4j Support Team, I am currently working on integrating my Neo4j Aura Professional instance with an n8n workflow via the HTTP API, but I am encountering persistent 403 Forbidden errors. The authentication credentials are correct, and I can successfully access the database via the Neo4j Browser and Cypher Shell. However, HTTP requests to the REST API (/db/neo4j/tx/commit) are being denied with the message: 403 - "Denied by administrative rules." Steps Taken: 1. Verified that the username and password are correct by logging into the Neo4j Browser. 2. Confirmed that the instance is running properly and accepts Cypher queries manually. 3. Constructed a proper HTTP request with Basic Authentication using an encoded Authorization: Basic header. 4. Tried different REST API endpoints (/db/neo4j/query/v2, /db/neo4j/tx/commit), all resulting in a 403 Forbidden error. 5. Checked the Neo4j documentation for any required settings related to enabling HTTP API access on Neo4j Aura. Request Details: • Method: POST • URL: https://<instance-id>. databases.neo4j.io/db/neo4j/tx/commit • Headers: Content-Type: application/json Accept: application/json; charset=UTF-8 Authorization: Basic <encoded-credentials> • Body: { "statements": [ { "statement": "MATCH (d:Domain) RETURN d.name AS name, d.description AS description, d.usage_frequency AS usage_frequency, d.created_at AS created_at, d.last_updated AS last_updated" } ] } • Response: { "errorMessage": "Forbidden - perhaps check your credentials?", "errorDescription": "<html><body><h1>403 Forbidden</h1>\nDenied by administrative rules.\n</body></html>\n" } Question: Is there a setting or permission in Neo4j Aura Professional that restricts HTTP API access? If so, how can I enable it to allow requests from external applications like n8n? I appreciate your assistance in resolving this issue. Best regards,
