Bulk SMS API is a high-quality SMS platform, enabling you to integrate any of your applications with our SMS message sending and receiving system. The main advantage of our system is its simplicity of implementation. The SMS message may have your company name or any phone number you own as sender name. Every message sent from our system has its own unique id, which allows you to receive confirmation of its delivery. Our Platinum Partner Operator status guarantees the highest quality text service at up to 8,000 messages a second. What’s more, our Bulk SMS API can personalize messages, receive delivery receipts, schedule messages and pull results from mobile forms and surveys into your app. Our SMS gateway can also handle tickets, enabling you to send individual vouchers or tickets.

How to start Bulk SMS API

To start using Bulk SMS API, you need to create an account on the USMSGH/SMS API website. Registration is completely free of charge. Your account is ready to use immediately after registration, but we recommend you to verify at least one sender name or number. The default name for all messages sent before verification is “INFO”.

In order to improve the security of the API interface, you may create a whitelist of IP addresses. IP addresses filter . Sending messages will be possible only from the whitelisted IP addresses (attempts at sending messages from other IPs will result in the following response: ERROR:105). IP addresses should be separated by semicolons

open API resources

USMSGH/ Bulk SMS API has more API resources beyond those mentioned in this documentation. They are documented in an openAPI standard here and are constantly extended and upgraded..


We recommend OAuth 2.0 authentication. To use OAuth, please generate a new token with selected scopes in the OAuth Tokens section of the Customer Portal. Authorization header will be necessary in request to our Bulk SMS API. If your environment doesn't support headers modification, please add the access_token parameter with its value to request. Please note that this is not a recommended authorization alternative and it has an adverse effect on security..
