How to integrate Exchange Rates API with Amazon SNS in 3 simple steps
- 1
Connect Exchange Rates API as your data source
Set up a source connector for Exchange Rates API in minutes. Estuary supports streaming (including CDC where available) and batch data capture through events, incremental syncs, or snapshots — without custom pipelines, agents, or manual configuration.
- 2
Configure Amazon SNS as your destination connector
Estuary supports intelligent schema handling, with schema inference and evolution tools that help align source and destination structures over time. It supports both batch and streaming data movement, reliably delivering data to Amazon SNS.
- 3
Deploy and Monitor Your End-to-End Data Pipeline
Launch your pipeline and monitor it from a single UI. Estuary guarantees exactly-once delivery, handles backfills and replays, and scales with your data — without engineering overhead.

Exchange Rates API connector details
The Exchange Rates API connector captures daily currency exchange rate data from the Exchange Rates API into Estuary collections, enabling historical and continuous tracking of foreign exchange values.
- Daily exchange rate ingestion: Retrieves daily exchange rate data across multiple supported currencies, starting from a specified date.
- Incremental sync: Automatically captures only new daily rates, keeping your collection updated without reloading previous data.
- Configurable base currency: Supports setting a custom base currency (default EUR) depending on your API plan.
- Weekend filtering: Includes an option to skip weekends, as financial markets are typically closed.
- Lightweight and easy to use: Ideal for educational, testing, or demo environments, offering a simple example of API-based ingestion.
💡 Tip: Free-tier API keys from the Exchange Rates API only support EUR as the base currency. Upgrade your plan to capture rates relative to other base currencies.

Amazon SNS connector details
The Amazon SNS materialization connector in Estuary publishes documents from Estuary collections to Amazon Simple Notification Service (SNS) topics. It can continuously deliver data from real-time or batch pipelines into SNS for event-driven applications, notifications, and downstream AWS workflows.
- Publishes Estuary collection documents directly to Amazon SNS topics
- One SNS event is published for every document processed from the source collection
- Delta-update semantics only, since SNS does not store rows or support merge-based updates
- Supports standard and FIFO SNS topics, with FIFO topic names ending in
.fifo - Multiple Estuary collections can be mapped to SNS topics using separate bindings
- Configurable AWS region for the SNS service
- AWS Access Key authentication using an Access Key ID and Secret Access Key
- AWS IAM role authentication for role-based access
- Custom AWS endpoint support for compatible services such as LocalStack
Because Amazon SNS is an event-streaming system rather than a database, Estuary does not merge or update previously published records. Every document flowing through the materialization results in a new event being published to the configured SNS topic.

Frequently Asked Questions
Is this integration suitable for production workloads?
Yes. Estuary pipelines are designed for production use, with exactly-once delivery semantics, automated backfills, and continuous operation at scale.
Can I control where my data runs and is processed?
Yes. Estuary offers multiple deployment options, including fully managed SaaS, private deployments, and bring-your-own-cloud (BYOC). This allows teams to control where their data plane runs and meet security, compliance, and networking requirements. Learn more about Estuary's security and deployment options.
Can I build this Exchange Rates API to Amazon SNS integration manually?
Yes, it's possible to build a manual pipeline using custom scripts, scheduled jobs, or open-source tools. However, manual approaches typically require ongoing maintenance, custom error handling, schema management, and operational overhead. Estuary simplifies this by providing a managed pipeline with built-in reliability, scaling, and monitoring.
