1) Package identity and separation

This folder is a standalone npm package for n8n:

• package file: n8n-nodes-edahab/package.json
• package name: n8n-nodes-edahab
• node runtime file: dist/nodes/Edahab/Edahab.node.js
• credential file: dist/credentials/EdahabApi.credentials.js

It is separate from the Python package (edahab on PyPI).

2) Features

• Implements all core eDahab endpoints required for workflows:
  • Issueinvoice
  • agentPayment
  • CheckInvoiceStatus
• usableAsTool: true for n8n AI Agent tool chains.
• Enforces currency in payment operations through constrained options (USD, SLSH).
• Uses official signing algorithm (SHA256(body + secret)) with stable serialized body.

3) Requirements

• n8n instance with community nodes enabled.
• Node.js/npm environment compatible with your n8n deployment.
• n8n credentials for eDahab API key and secret.

4) Install and build

From this folder:

npm install
npm run build

Build output includes:

• dist/nodes/Edahab/Edahab.node.js
• dist/credentials/EdahabApi.credentials.js
• dist/transport/edahabRequest.js
• dist/nodes/Edahab/eDahab.png

5) Install into n8n

Local path install (recommended for development)

mkdir -p ~/.n8n/nodes
cd ~/.n8n/nodes
npm install /absolute/path/to/edahab/n8n-nodes-edahab

Restart n8n after install.

Install from npm registry

npm install n8n-nodes-edahab

Then restart n8n.

6) AI Agent tool usage

The node is usable as an n8n AI tool because:

• node definition sets usableAsTool: true
• operations are explicit and deterministic
• currency values are constrained to avoid invalid API calls

In AI agent workflows, choose the eDahab node as a tool and map inputs from the agent context.

7) Credentials reference

Credential type: eDahab API

Security note: API secret is not sent directly, only used to derive hash.

8) Node operations reference

Resource: Payment

Operation: Collect from Customer (Issueinvoice)

Parameters:

• edahabNumber (string, required)
• amount (number, required)
• agentCode (string, required)
• currency (options, required): USD or SLSH
• failOnInvoiceError (boolean)

Behavior:

• Calls POST Issueinvoice?hash=...
• If failOnInvoiceError=true, non-zero StatusCode fails node

Operation: Send Credit (agentPayment)

Parameters:

• phoneNumber (string, required)
• transactionAmount (number, required)
• transactionId (string, required)
• currencyAgent (options, required): USD or SLSH

Behavior:

• Calls POST agentPayment?hash=...
• Returns parsed response JSON
• Does not apply invoice-style StatusCode failure logic by default

Resource: Invoice

Operation: Verify Status (CheckInvoiceStatus)

Parameters:

• invoiceId (string, required)
• failOnInvoiceErrorVerify (boolean)

Behavior:

• Calls POST CheckInvoiceStatus?hash=...
• Can fail node on non-zero StatusCode when toggle enabled

9) Request signing behavior

The node performs these steps before each API request:

1. Build sorted compact JSON body
2. Compute hash = SHA256(body + apiSecret)
3. Send POST to baseUrl + endpoint + ?hash=...

This matches eDahab docs and the companion Python SDK behavior.

10) Error handling behavior

• Network/HTTP issues are raised as node operation errors.
• Invalid JSON responses fail execution.
• Invoice operations can be strict or permissive based on fail toggles.
• continueOnFail behavior is respected and returns item-level error payload.

11) Publish to npm

npm run build
npm publish --access public

If your npm account has 2FA enabled for publish:

npm publish --access public --otp=123456

12) Troubleshooting

• Node not visible in n8n: restart n8n and verify package installed under .n8n/nodes.
• Icon missing: confirm dist/nodes/Edahab/eDahab.png exists after npm run build.
• Credential/status errors: verify API key/secret and base URL.
• StatusCode failures: check status docs and disable strict toggle if you want soft handling.
