| 22 | +<summary>Do you offer a sandbox or testing environment?</summary> |
| 23 | + |
| 24 | +Yes, we provide a sandbox environment for testing your integrations. The sandbox uses the same API endpoints but with test data and doesn't affect your production environment. |
| 25 | + |
| 26 | +- Sandbox Base URL: `https://sandbox-api.example.com` |
| 27 | +- Production Base URL: `https://api.example.com` |
| 28 | + |
| 29 | +Learn more about our [testing environments](/getting-started/environments). |

| 31 | +</details> |
| 32 | + |
| 33 | +<details> |
| 34 | +<summary>What programming languages do you support?</summary> |
| 35 | + |
| 36 | +Our API is RESTful and can be used with any programming language that supports HTTP requests. We provide official SDKs for: |

| 47 | +</details> |
| 48 | + |
| 49 | +## Authentication |
| 50 | + |
| 51 | +<details> |
| 52 | +<summary>How do I authenticate my API requests?</summary> |
| 53 | + |
| 54 | +We use API key authentication. Include your API key in the request header: |
| 55 | + |
| 56 | +```bash |
| 57 | +Authorization: Bearer YOUR_API_KEY |
| 58 | +``` |
| 59 | + |
| 60 | +You can generate and manage your API keys in the [developer dashboard](https://developer.example.com/dashboard). |
| 61 | + |
| 62 | +For detailed authentication information, see our [Authentication Guide](/api-reference/authentication). |
| 63 | + |
| 64 | +</details> |
| 65 | + |
| 66 | +<details> |
| 67 | +<summary>How do I keep my API key secure?</summary> |
| 68 | + |
| 69 | +To keep your API key secure: |
| 70 | + |
| 71 | +- Never expose your API key in client-side code |
| 72 | +- Store API keys as environment variables |
| 73 | +- Use different keys for different environments (development, staging, production) |
| 74 | +- Regularly rotate your API keys |
| 75 | +- Monitor your API key usage in the dashboard |
| 76 | + |
| 77 | +See our [Security Best Practices](/security/best-practices) for more information. |
| 78 | + |
| 79 | +</details> |
| 80 | + |
| 81 | +<details> |
| 82 | +<summary>Can I use multiple API keys for the same account?</summary> |
| 83 | + |
| 84 | +Yes, you can create multiple API keys for different purposes or environments. Each key can have different permissions and rate limits configured. |
| 85 | + |
| 86 | +To manage your API keys, visit your [developer dashboard](https://developer.example.com/dashboard/api-keys). |
| 87 | + |
| 88 | +</details> |
| 89 | + |
| 90 | +## Rate Limits |
| 91 | + |
| 92 | +<details> |
| 93 | +<summary>What are the rate limits for the API?</summary> |
| 94 | + |
| 95 | +Our rate limits vary by plan: |
| 96 | + |
| 97 | +- **Free Plan**: 1,000 requests per hour |
| 98 | +- **Pro Plan**: 10,000 requests per hour |
| 99 | +- **Enterprise Plan**: Custom limits available |
| 100 | + |
| 101 | +Rate limits are enforced per API key. When you exceed the limit, you'll receive a `429 Too Many Requests` response. |
| 102 | + |
| 103 | +For current rate limit information, see our [Rate Limits documentation](/api-reference/rate-limits). |
| 104 | + |
| 105 | +</details> |
| 106 | + |
| 107 | +<details> |
| 108 | +<summary>How can I check my current rate limit usage?</summary> |
| 109 | + |
| 110 | +Rate limit information is included in every API response header: |
| 111 | + |
| 112 | +- `X-RateLimit-Limit`: Your rate limit ceiling for that given request |
| 113 | +- `X-RateLimit-Remaining`: Number of requests left for the time window |
| 114 | +- `X-RateLimit-Reset`: UTC date/time when the rate limit resets |
| 115 | + |
| 116 | +You can also monitor usage in your [developer dashboard](https://developer.example.com/dashboard/usage). |
| 117 | + |
| 118 | +</details> |
| 119 | + |
| 120 | +<details> |
| 121 | +<summary>What happens when I hit the rate limit?</summary> |
| 122 | + |
| 123 | +When you exceed your rate limit, the API will return: |
| 124 | + |
| 125 | +- HTTP Status Code: `429 Too Many Requests` |
| 126 | +- Error message explaining the rate limit exceeded |
| 127 | +- `Retry-After` header indicating when you can make requests again |
| 128 | + |
| 129 | +Implement exponential backoff in your application to handle rate limit responses gracefully. |
| 130 | + |
| 131 | +</details> |
| 132 | + |
| 133 | +## Error Handling |
| 134 | + |
| 135 | +<details> |
| 136 | +<summary>What HTTP status codes does the API return?</summary> |

| 141 | +- **201**: Created |
| 142 | +- **400**: Bad Request |
| 143 | +- **401**: Unauthorized |
| 144 | +- **403**: Forbidden |
| 145 | +- **404**: Not Found |
| 146 | +- **429**: Too Many Requests |

| 149 | +Each error response includes a detailed error message and error code. See our [Error Handling Guide](/api-reference/errors) for complete details. |
| 150 | + |
| 151 | +</details> |
| 152 | + |
| 153 | +<details> |
| 154 | +<summary>How should I handle API errors in my application?</summary> |
| 155 | + |
| 156 | +Best practices for error handling: |
| 157 | + |
| 158 | +1. Always check the HTTP status code |
| 159 | +2. Parse the error response for detailed information |
| 160 | +3. Implement retry logic for temporary errors (5xx codes) |
| 161 | +4. Log errors for debugging purposes |
| 162 | +5. Provide meaningful error messages to your users |
| 163 | + |
| 164 | +Example error response structure: |
| 165 | + |
| 166 | +```json |
| 167 | +{ |
| 168 | + "error": { |
| 169 | + "code": "invalid_parameter", |
| 170 | + "message": "The 'email' parameter is required", |
| 171 | + "details": "Please provide a valid email address" |
| 172 | + } |
| 173 | +} |
| 174 | +``` |

| 207 | + |
| 208 | +<details> |
| 209 | +<summary>How do I handle pagination in API responses?</summary> |
| 210 | + |
| 211 | +Large result sets are paginated using cursor-based pagination: |
| 212 | + |
| 213 | +```json |
| 214 | +{ |
| 215 | + "data": [...], |
| 216 | + "pagination": { |
| 217 | + "has_more": true, |
| 218 | + "next_cursor": "eyJpZCI6MTIzfQ==" |
| 219 | + } |
| 220 | +} |
| 221 | +``` |
| 222 | + |
| 223 | +Use the `next_cursor` value in your next request to get the next page of results. |
| 224 | + |
| 225 | +See our [Pagination Guide](/api-reference/pagination) for detailed examples. |
| 226 | + |
| 227 | +</details> |
| 228 | + |
| 229 | +<details> |
| 230 | +<summary>Can I filter or sort API responses?</summary> |
| 231 | + |
| 232 | +Yes, many endpoints support filtering and sorting through query parameters: |
| 233 | + |
| 234 | +- **Filtering**: `?filter[status]=active&filter[type]=premium` |
| 235 | +- **Sorting**: `?sort=created_at&order=desc` |
| 236 | +- **Field selection**: `?fields=id,name,email` |
| 237 | + |
| 238 | +Available filters and sort options vary by endpoint. Check the specific endpoint documentation for supported parameters. |
