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,
