1. Copy the curl example above.
2. Paste the curl call into your favorite text editor.
3. Copy your API key and paste it in the "Authorization" header.
4. In the data section, specify the "to", "from", and "reply to" names and email addresses and enter a subject.
5. Copy the code and paste it in your terminal.
6. Hit Enter.
7. Check the inbox of the address you specified as the "to" email and see your message!

• Authorization Header: To authenticate, add an Authorization header to your API request that contains an API Key.
• API Keys: HandySends Web API v3 supports the use of API Keys. API Keys allow you to use another method of authentication separate from your account username and password. API Keys add an additional layer of security for your account and can be assigned specific permissions to limit which areas of your account they may be used to access. API Keys can be generated in your account. To use keys, you must set a plain text header named “Authorization” with the contents of the header being “Bearer XXX” where XXX is your API Secret Key.
• Example Header: GET https://api.handysends.com/v3/resource HTTP/1.1 Authorization: Bearer Your.API.Key-HERE curl -X "GET" "https://api.handysends.com/v3/templates" -H "Authorization: Bearer Your.API.Key-HERE" -H "Content-Type: application/json"

Transactional email services facilitate email services between the sender and the recipients. They typically carry the information of the recipient, according to their actions and needs. They have high open rates. HandySends transactional email service provides personalization component with v3 API in the creation of accounts, enable email activity feed, supports API & SMTP Integration to support all email requirements for low leverage and to send emails with real-time email activity to measure your work.

Transnational emails are based on the user's actions. They are used to help the customers at the time of troubleshooting. For instance, transactional emails like password reset help the users regain control of their block account by resetting passwords. In such cases inserting an unsubscribe option, is not advisable. An unsubscribe option is to let your email service providers know that you're not interested in receiving more emails. Transactional emails should not have the same meaning by including the unsubscribe option. Instead of using the unsubscribe option in transnational email, you can include the email preference link “update how we send you email”. Be honest when adding links as they are valued by email service providers.
