Frequently Asked Questions (FAQ)

Overview

This page will answer common questions about Edge API integration, including:

• Authentication
• Rate Limits
• Integration
• Troubleshooting

Authentication

How do I get API credentials?

See Integration Onboarding for account creation and credential generation.

How long do access tokens last?

Access tokens expire after 1 hour. Your application should request a new token when needed. See Integration Onboarding for credential setup details.

Can I use the same credentials for sandbox and production?

No. Sandbox and production use separate credentials for security. You'll receive different API keys for each environment.

Rate Limits

What are the rate limits?

• Standard tier: 500 requests/minute
• Professional tier: 2,000 requests/minute
• Enterprise tier: Custom limits

Rate limits are communicated during onboarding.

• C# / .NET - Full featured SDK
• JavaScript/TypeScript - Node.js and browser

You can also use any language that supports HTTPS and JSON via direct REST API calls.

Do you have a sandbox environment?

Troubleshooting

Why am I getting 401 errors?

401 Unauthorized typically means:

• Access token expired (tokens last 1 hour)
• Invalid credentials
• Token not included in request

Review token setup in Integration Onboarding.

How do I avoid non-printable character issues?

Printable Characters

Ids and text fields in EDGE for Windows must be printable and therefore the API validates any text it receives before integrating it with EDGE for Windows data. You can head off any validation issues by sanitizing your string before they are sent through our API using the following Regex Expression to validate your text:

\[\^ -\~\]+

This Regex Expression is looking for a match with any character that is below ASCII32 and above ASCII126.

The following method demonstrates the validation in C#:

public static bool IsValid(this string arg)
{
	if (arg == null) throw new ArgumentNullException();
	string asciiBelow32AndAbove126 = "\[\^ -\~\]+";
	Regex regEx = new Regex(asciiBelow32AndAbove126);
	return !regEx.IsMatch(arg);
}

Why am I getting 429 errors?

429 Too Many Requests means you've exceeded your rate limit. Wait 60 seconds and retry with exponential backoff.

Where can I find error codes?
