# Tindakan untuk Step Functions menggunakan AWS SDKs
Contoh kode berikut menunjukkan cara melakukan tindakan Step Functions individual dengan AWS SDKs. Setiap contoh menyertakan tautan ke GitHub, di mana Anda dapat menemukan instruksi untuk mengatur dan menjalankan kode.
Kutipan ini memanggil Step Functions API dan merupakan kutipan kode dari program yang lebih besar yang harus dijalankan dalam konteks. Anda dapat melihat tindakan dalam konteks di[Skenario untuk Step Functions menggunakan AWS SDKs](sfn_code_examples_scenarios.md).
Contoh berikut hanya mencakup tindakan yang paling umum digunakan. Untuk daftar lengkapnya, lihat [Referensi AWS Step Functions API](https://docs.aws.amazon.com/step-functions/latest/apireference/Welcome.html).
